Rubber, EPDM and the fibre-reinforced water hoses are vulcanised elastomers governed by the rubber hose standards. PVC, polyurethane and PTFE are thermoplastics governed by separate plastics hose standards. That one split explains most of the differences in temperature range, pressure rating and chemical resistance you will see on a data sheet.<\/p>\n\n\n\n<p>This guide walks through each of the five families in the order a specification decision actually happens. It covers what makes a material an elastomer or a thermoplastic, and the published limits each family is held to. It then runs a property-by-property hose material comparison across temperature, chemical compatibility, pressure and abrasion. The food and drinking-water contact standards, and the failure patterns of a mismatched choice, follow at the end.<\/p>\n\n\n\n<p>It is written for people who have to defend a material choice in writing. That includes procurement teams comparing quotations, maintenance engineers replacing a hose that failed early, OEM designers specifying a hose for a new machine, and distributors deciding what to stock. No product in this guide is described as the best overall, because the best hose material is always the one whose published limits cover the fluid, the temperature and the pressure of the specific line.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-are-the-types-of-flexible-hose-materials-the-direct-answer\">What Are the Types of Flexible Hose Materials? The Direct Answer<\/h2>\n\n\n\n<p>Five families cover almost every flexible hose sold for water, air, oil, chemical and food service: rubber, EPDM, PVC, polyurethane and PTFE. A hose material is defined by its base polymer rather than by its colour, brand or cover finish, and each family carries its own published temperature band plus its own reinforcement type. What are hoses made of? The answer has three parts, and each one sets a different limit: the tube sets the fluid and temperature limits, the reinforcement sets the hose working pressure, and the cover sets the abrasion and weather life.<\/p>\n\n\n\n<p>There are also five flexible hose types by construction, and they cut across the material families rather than replacing them:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Textile-braided hose \u2014 the general-purpose construction behind water, air and multipurpose hose<\/li>\n\n\n\n<li>Wire-braided or spiral hose \u2014 the pressure construction used where textile braid is not strong enough<\/li>\n\n\n\n<li>Helix-wire hose \u2014 the suction construction that resists collapse under vacuum<\/li>\n\n\n\n<li>Corrugated hose \u2014 thin-wall hose that bends tightly, common in PTFE and ducting service<\/li>\n\n\n\n<li>Unreinforced tube \u2014 soft, low-pressure hose for light duty and laboratory use<\/li>\n<\/ul>\n\n\n\n<p>The table below is the short version of this article: the five material families, the standard that fixes their main published duty, and the one limitation that most often rules each one out.<\/p>\n\n\n\n<p>Types of flexible hose materials: base polymer family, the standard that governs the main duty, and the limitation that rules each one out most often.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th scope=\"col\">Material<\/th><th scope=\"col\">Polymer family<\/th><th scope=\"col\">Standard governing its main duty<\/th><th scope=\"col\">Temperature range<\/th><th scope=\"col\">Where it wins<\/th><th scope=\"col\">What most often rules it out<\/th><\/tr><\/thead><tbody><tr><td>Rubber (natural rubber, SBR)<\/td><td>Vulcanised elastomer<\/td><td>ISO 1403 for textile-reinforced general-purpose water hose; ISO 4641 for water suction and discharge<\/td><td>\u221225 \u00b0C to +70 \u00b0C as stated in ISO 1403 for general-purpose water hose<\/td><td>Abrasion resistance, low cost, flexibility at low temperature, suction duty with helix wire<\/td><td>Swelling in oil and fuel; ozone and sunlight cracking of the cover<\/td><\/tr><tr><td>EPDM<\/td><td>Vulcanised elastomer<\/td><td>SAE J20 for automotive coolant hose<\/td><td>\u221240 \u00b0C to +135 \u00b0C typical for EPDM coolant hose, with a high-temperature class declared above 125 \u00b0C<\/td><td>Weather, ozone and hot-water resistance; outdoor and engine-bay life<\/td><td>Oil, fuel and hydrocarbon service, where the tube swells<\/td><\/tr><tr><td>PVC<\/td><td>Thermoplastic<\/td><td>ISO 6224 for textile-reinforced thermoplastics water hose<\/td><td>\u221210 \u00b0C to +60 \u00b0C as commonly declared for PVC general-purpose water hose<\/td><td>Lowest cost per metre, light weight, clear and coloured options<\/td><td>Heat above the softening range, cold stiffness, plasticiser migration, kinking<\/td><\/tr><tr><td>Polyurethane (PU)<\/td><td>Thermoplastic<\/td><td>ISO 5774 for textile-reinforced plastics hose for compressed air<\/td><td>\u221210 \u00b0C to +60 \u00b0C as stated in ISO 5774 for compressed-air hose<\/td><td>Abrasion and cut resistance, cold-weather flexibility, light weight<\/td><td>Hydrolysis in hot water and steam; esters, ketones and some concentrated acids<\/td><\/tr><tr><td>PTFE<\/td><td>Fluoropolymer<\/td><td>SAE 100R14, a style in SAE J517, for braided PTFE hose; ISO 10380 for corrugated assemblies<\/td><td>Above the +135 \u00b0C EPDM ceiling, the highest of the other four; the exact limit is set by the assembly grade<\/td><td>Near-universal chemical resistance and the highest temperature ceiling of the five<\/td><td>Cost, low flexibility, and the need for crimped end fittings rather than clamps<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero.jpg\" alt=\"Coils of five flexible hose materials on a workshop bench: black rubber water hose, black EPDM coolant hose, clear blue PVC hose, orange polyurethane air hose and a stainless steel braided PTFE hose\" class=\"wp-image-5575\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/types-of-flexible-hose-materials-hero-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 1.

The Split That Decides Everything<\/h2>\n\n\n\n<p>Every flexible hose is either an elastomer or a thermoplastic, and the difference is not marketing language. It is a difference in molecular structure that the standards themselves treat as a boundary, which is why the same duty \u2014 general-purpose water \u2014 has one specification for rubber hose and a separate one for thermoplastics hose. The same boundary runs through the other flexible hose types, because a suction hose and a pressure hose are separated by their reinforcement while the tube polymer is what fixes the fluid and temperature limits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-the-two-families-have-separate-product-standards\">Why the Two Families Have Separate Product Standards<\/h3>\n\n\n\n<p>A rubber hose and a thermoplastic hose with the same bore, the same braid and the same appearance are held to different documents. ISO maintains one specification for textile-reinforced rubber water hose and another for textile-reinforced thermoplastics water hose, and the two do not state the same temperature range. That divergence is the single most useful fact to carry into a hose material comparison, because it comes from the standards rather than from a supplier&#8217;s brochure.<\/p>\n\n\n\n<p>The four documents that cover the bulk of water and air hose duty are listed below, with the figures each supplies.<\/p>\n\n\n\n<p>Operating limits for the four specifications that cover most general-purpose water and compressed-air hose.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th scope=\"col\">Est\u00e1ndar<\/th><th scope=\"col\">What it covers<\/th><th scope=\"col\">Types it specifies<\/th><th scope=\"col\">Operating temperature<\/th><th scope=\"col\">Stated pressure or other limit<\/th><\/tr><\/thead><tbody><tr><td>ISO 1403<\/td><td>Rubber hoses, textile-reinforced, for general-purpose water applications<\/td><td>Three types of general-purpose textile-reinforced rubber water hose<\/td><td>\u221225 \u00b0C to +70 \u00b0C<\/td><td>Maximum working pressure up to 25 bar.

A hose that must deliver water at 65 \u00b0C and stay flexible below \u221215 \u00b0C is therefore a rubber hose by construction rather than by preference.<\/p>\n\n\n\n<p>The compressed-air specification does not publish one pressure rating per type. ISO 5774 publishes two: the rating at 23 \u00b0C and the rating at the top of the temperature range. Any air hose quotation that states a single working pressure without stating the temperature it applies to is an incomplete quotation, and the drop between those two ratings is the reason.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-vulcanisation-changes-that-extrusion-cannot\">What Vulcanisation Changes That Extrusion Cannot<\/h3>\n\n\n\n<p>Rubber hose starts as an uncured compound that is shaped and then vulcanised, a chemical crosslinking step that locks the polymer into a three-dimensional network. Once crosslinked, the tube cannot be melted and re-formed, so a rubber hose recovers its shape after it is stretched, compressed or bent, and it keeps useful elasticity down to the low end of its range.<\/p>\n\n\n\n<p>Thermoplastic hose is extruded and cooled. No crosslink forms, so the tube softens progressively as it approaches its softening range and re-hardens when it cools. That behaviour is an advantage in manufacturing, because a PVC or polyurethane hose can be welded, heat-formed or coiled tightly, and it is a constraint in service, because the pressure the hose can hold falls as the temperature rises. ISO 5774 states that fall openly: the heavy-service type holds 16 bar at 23 \u00b0C and 11 bar at 60 \u00b0C.<\/p>\n\n\n\n<p>Two further consequences follow from the same structural difference, and both show up in real failures. A thermoplastic tube softens before it fails, so an overheated PVC hose tends to balloon and then split at a kink rather than burst cleanly. A vulcanised tube hardens instead, so an aged rubber or EPDM cover cracks and then exposes the reinforcement to abrasion. That is also why the answer to what are hoses made of never comes from the tube alone.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram.jpg\" alt=\"Diagram comparing vulcanised elastomer hose and thermoplastic hose structure, showing a crosslinked rubber tube, a linear thermoplastic tube, and the textile braid and helix wire reinforcement layers common to both\" class=\"wp-image-5576\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/flexible-hose-elastomer-thermoplastic-structure-diagram-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 2. The structural difference: a crosslinked elastomer tube that cannot be re-melted against an extruded thermoplastic tube that softens as it warms. Both families use the same reinforcement options.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rubber-the-baseline-flexible-hose-material\">Rubber: The Baseline Flexible Hose Material<\/h2>\n\n\n\n<p>Rubber is the oldest of the types of flexible hose materials and still the default for water, air and multipurpose service. Natural rubber and SBR are the two compounds used for general-purpose water hose, and both are specified by ISO 1403. That document covers three types of textile-reinforced rubber water hose, across a stated operating range of \u221225 \u00b0C to +70 \u00b0C and a maximum working pressure of up to 25 bar.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-the-rubber-water-hose-standard-covers-and-what-it-excludes\">What the Rubber Water Hose Standard Covers and What It Excludes<\/h3>\n\n\n\n<p>The most useful thing about ISO 1403 is not the temperature range. It is the exclusion list. The standard states its own exclusion list, and potable water, washing-machine inlets and firefighting duty are all on it. A general-purpose rubber water hose offered for any of those duties is therefore being used outside its own specification. A potable water hose has to be declared against a drinking-water standard instead.<\/p>\n\n\n\n<p>Suction and discharge water hose is specified separately. ISO 4641 covers textile-reinforced, smooth-bore rubber hose for water suction and discharge in three types separated by operating duty, with ambient temperatures of \u221225 \u00b0C to +70 \u00b0C and water temperatures during operation of 0 \u00b0C to +70 \u00b0C. Note the lower bound on the water figure: the ambient range goes colder than the water range, because the concern at the bottom of the range is the flexibility of the hose itself rather than freezing water inside it.<\/p>\n\n\n\n<p>The specification limits that matter for a rubber water hose order are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The standard the hose is declared against, which decides the temperature range it is entitled to claim<\/li>\n\n\n\n<li>Whether the hose is discharge duty only, or suction and discharge duty with helix wire<\/li>\n\n\n\n<li>The pressure class, since the same standard covers constructions up to 25 bar<\/li>\n\n\n\n<li>Whether the intended fluid falls inside the standard&#8217;s scope or is on its exclusion list<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-rubber-outperforms-the-other-materials\">Where Rubber Outperforms the Other Materials<\/h3>\n\n\n\n<p>Natural rubber and SBR earn their place on three properties rather than on price alone. Abrasion resistance is the first: a rubber cover tolerates dragged hose and rough ground better than a thin-wall thermoplastic cover of the same weight. Low-temperature flexibility is the second, and it is where rubber separates itself most clearly from PVC. The rubber water hose specification starts at \u221225 \u00b0C, while the thermoplastics specification starts at \u221210 \u00b0C.<\/p>\n\n\n\n<p>Elastic recovery is the third property, and it is why rubber hose resists kinking under a bend radius that would flatten a soft PVC hose. Between them, those three properties explain why rubber still accounts for most flexible hose types sold for general water duty.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-does-a-rubber-hose-fail-first\">Where Does a Rubber Hose Fail First?<\/h3>\n\n\n\n<p>Oil and fuel are the first failure for natural rubber. A hydrocarbon fluid swells the tube, the swelling reduces the bore and softens the wall, and the hose eventually weeps at a clamped joint or bursts behind the fitting. Weather is the second: unsaturated rubbers crack under ozone and ultraviolet exposure, which is why an unprotected natural rubber hose left outdoors develops a crazed cover.<\/p>\n\n\n\n<p>The practical rule that follows is short. Natural rubber and SBR are water and air materials, not fluid-transfer materials, and any line carrying oil, fuel or a solvent belongs to a different family in the table above.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"epdm-the-outdoor-and-hot-water-rubber\">EPDM: The Outdoor and Hot-Water Rubber<\/h2>\n\n\n\n<p>EPDM is a synthetic rubber built on a saturated polymer backbone, and that backbone is the reason it survives outdoors. It is the compound behind automotive coolant and heater hose, and behind a large share of industrial hot-water and washdown hose. It is also the standard answer when a hose has to live in sunlight, in ozone and in hot water at the same time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-epdm-resists-weather-that-destroys-natural-rubber\">Why EPDM Resists Weather That Destroys Natural Rubber<\/h3>\n\n\n\n<p>Ozone and ultraviolet light attack the carbon-carbon double bonds in unsaturated rubbers such as natural rubber. EPDM&#8217;s backbone is saturated, so the same exposure produces far less chain scission at the surface. The practical result is a cover that keeps its integrity through years of outdoor storage and open-air routing. An EPDM hose left on an outdoor rack over a season still looks like a hose, while a natural rubber hose beside it has developed a cracked, crazed surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-the-coolant-hose-standard-fixes-for-epdm\">What the Coolant Hose Standard Fixes for EPDM<\/h3>\n\n\n\n<p>The EPDM figures used in automotive and equipment cooling systems come from SAE J20, which covers reinforced hose for engine coolant systems in designations 20R1 to 20R5. The high-temperature designation in SAE J20 applies to hose of any of those types required to operate in an environment above 125 \u00b0C. The \u221240 \u00b0C to +135 \u00b0C figure is the typical EPDM coolant-hose service range rather than a band stated by the standard itself. Curved 20R3 and 20R4 hose is additionally qualified by heat ageing.<\/p>\n\n\n\n<p>One limit of this class is worth noticing. Coolant hose of this class is not suitable for fuel, oil or brake fluid service, and that restriction is a property of the EPDM compound rather than of the hose construction. EPDM swells in hydrocarbons quickly enough to make the hose unfit, and no amount of reinforcement changes it.<\/p>\n\n\n\n<p>Where an EPDM hose is specified, the figures that should appear on the order are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The SAE J20 designation and whether the high-temperature class applies<\/li>\n\n\n\n<li>The coolant or water temperature measured at the hose rather than the temperature at the pump<\/li>\n\n\n\n<li>The system pressure including the relief valve setting, not the nominal pump rating<\/li>\n\n\n\n<li>Confirmation that the fluid is water, coolant or steam and not a hydrocarbon<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-epdm-is-the-wrong-material\">Where EPDM Is the Wrong Material<\/h3>\n\n\n\n<p>EPDM is a poor choice in four situations, and all four are fluid-driven rather than temperature-driven. Mineral and hydraulic oil are the first, fuel and diesel the second, and any aromatic or aliphatic solvent the third. Phosphate-ester hydraulic fluid is the fourth: EPDM tolerates it while the same fluid destroys nitrile, so a fleet running both mineral and phosphate-ester fluids cannot standardise on a single tube compound.<\/p>\n\n\n\n<p>Steam is the case where EPDM is right, provided the hose is built for it. Saturated steam service has its own specification rather than being treated as hot water, so a hose declared for steam duty is the only correct choice above the water range of the general-purpose standards. Where the duty is hot water rather than steam, an EPDM hose rated for the water temperature is normally the lower-cost answer. Our <a href=\"https:\/\/www.henghuahose.com\/es\/product\/epdm-steam-hose-170%e2%84%83\/\" target=\"_blank\" rel=\"noopener\">EPDM steam hose<\/a> is built for the steam case, and the wider water hose range covers the ambient and hot-water duties above.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"pvc-the-lowest-cost-thermoplastic\">PVC: The Lowest-Cost Thermoplastic<\/h2>\n\n\n\n<p>PVC is the material behind most garden hose and a large share of light industrial water and suction hose, and it is chosen for cost, weight and clarity rather than for temperature or chemical performance. It is a thermoplastic, so it is governed by the thermoplastics water hose specification rather than the rubber one, and the published range of general-purpose PVC water hose is narrower than the rubber range at both ends.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-a-pvc-hose-is-made-and-why-it-costs-less\">How a PVC Hose Is Made and Why It Costs Less<\/h3>\n\n\n\n<p>A PVC hose is extruded from a compound of PVC resin, plasticiser, stabiliser and filler, and the plasticiser is what turns a rigid plastic into a flexible hose. Because the process is continuous extrusion rather than a curing step, cost per metre is low and wall thickness can be held to tight tolerances. The same process allows a clear or tinted wall, which is why PVC dominates applications where the operator needs to see the fluid or where colour is part of the product identity.<\/p>\n\n\n\n<p>The trade-off is that the plasticiser is a mobile component. It can migrate out of the wall over time and under heat, and the hose hardens from the inside out until it is no longer flexible enough to be coiled.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-the-thermoplastics-water-hose-standard-fixes\">What the Thermoplastics Water Hose Standard Fixes<\/h3>\n\n\n\n<p>ISO 6224 covers textile-reinforced thermoplastics hose for general-purpose water applications and designates three types by pressure rating. PVC hose in general-purpose water grades is normally declared across \u221210 \u00b0C to +60 \u00b0C, a band to confirm on the supplier&#8217;s declaration rather than read from the standard. That band is narrower at both ends than the rubber water hose band, which is why the duty moves to rubber once the line runs cold enough to stiffen PVC or hot enough to soften it.<\/p>\n\n\n\n<p>The limits a PVC hose buyer should confirm before ordering are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The reinforcement, since unreinforced PVC tube holds far less pressure than textile-braided PVC hose<\/li>\n\n\n\n<li>The declared temperature range, because a general-purpose PVC hose is not a hot-water hose<\/li>\n\n\n\n<li>The plasticiser type, which affects flexibility retention and whether food or drinking-water contact is claimed<\/li>\n\n\n\n<li>The pressure class and whether the duty is discharge only or suction and discharge<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-limits-end-a-pvc-hose\">What Limits End a PVC Hose?<\/h3>\n\n\n\n<p>Four failure modes account for most PVC hose complaints. Heat above the declared range softens the wall, so the hose balloons under pressure and splits at a bend. Cold below the declared range stiffens it, so a hose that flexed easily at 20 \u00b0C cracks when it is uncoiled at \u221215 \u00b0C. Plasticiser loss over years of service hardens the wall until it kinks permanently at the same point. A kink under pressure then concentrates stress on one section of wall, which is why a failed PVC hose usually fails where it was kinked rather than along the straight run.<\/p>\n\n\n\n<p>A fifth limit is chemical rather than mechanical. PVC is compatible with water and with many dilute acids and bases, but it is not a universal chemical hose, and strong solvents, esters and ketones attack the wall. Chemical duty belongs to a hose declared against a chemical hose specification, not to a garden hose pressed into service. The same caution applies to the other types of hoses: a material that passes for water is not thereby qualified for the fluid in the next line.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"polyurethane-pu-abrasion-and-cold-weather-performance\">Polyurethane (PU): Abrasion and Cold-Weather Performance<\/h2>\n\n\n\n<p>Polyurethane is the thermoplastic chosen when a hose has to survive being dragged, cut and flexed rather than when it has to survive heat. It is the dominant material for pneumatic tool hose, for coiled air hose and for abrasive-duty lines, and it is the material most often described as outlasting the PVC hose it replaces in the same application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-pu-outlasts-pvc-in-abrasive-air-service\">Why PU Outlasts PVC in Abrasive Air Service<\/h3>\n\n\n\n<p>The abrasion and cut resistance of a polyurethane wall is higher than that of a plasticised PVC wall of comparable thickness, so a PU air hose dragged across a workshop floor or a concrete slab wears through far more slowly. Polyurethane also stays flexible at low temperature, which is why a coiled PU air hose uncoils in a cold workshop where an equivalent PVC hose has gone stiff.<\/p>\n\n\n\n<p>Weight is part of the same decision. A PU hose of a given bore and pressure class is lighter than the rubber hose it replaces, which matters on a tool that an operator carries all day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-the-compressed-air-hose-standard-fixes\">What the Compressed-Air Hose Standard Fixes<\/h3>\n\n\n\n<p>ISO 5774 covers textile-reinforced plastics hose for compressed air in four types, across a stated temperature range of \u221210 \u00b0C to +60 \u00b0C. Its most useful feature is that it publishes the working pressure at two temperatures rather than one: 7, 10, 16 and 25 bar at 23 \u00b0C, falling to 4.5, 6.5, 11 and 13 bar at 60 \u00b0C.<\/p>\n\n\n\n<p>That pair of columns is the whole argument for treating the hose working pressure as a temperature-dependent figure. A light-service hose rated at 7 bar is a 4.5 bar hose at the top of its range. Compressed air heats up as it is compressed, so an air line running at 60 \u00b0C is a normal operating condition rather than an edge case.<\/p>\n\n\n\n<p>The figures that should be stated on a PU air hose order are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The service class (light, medium, heavy or heavy for mining) and the pressure at the working temperature<\/li>\n\n\n\n<li>The compressor cut-out pressure and the relief valve setting, which is the true ceiling<\/li>\n\n\n\n<li>Whether the hose is straight or coiled, since coil memory affects the deployed length and the working radius<\/li>\n\n\n\n<li>The oil content of the air, because some compressor lubricants and condensate attack the tube<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-polyurethane-fails-hydrolysis-and-hot-water\">Where Polyurethane Fails: Hydrolysis and Hot Water<\/h3>\n\n\n\n<p>Polyurethane&#8217;s weakness is hydrolysis. Polyurethane compounds are degraded by sustained contact with hot water, and the failure develops from the inside: the tube softens, then becomes tacky, then loses wall strength. Hot-water service is therefore not a polyurethane application, and an EPDM or rubber hose is the correct choice at the same bore.<\/p>\n\n\n\n<p>The chemical limits are narrower than the abrasion figures suggest. Polyurethane is attacked by esters, ketones and some concentrated acids and bases, so it is not the material for a chemical transfer line even though it is an excellent material for the abrasive duty alongside one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ptfe-the-chemical-and-high-temperature-outlier\">PTFE: The Chemical and High-Temperature Outlier<\/h2>\n\n\n\n<p>PTFE is the fluoropolymer that sits outside the normal comparison. It is chosen for two properties that no other material in this guide approaches: chemical inertness against almost every industrial fluid, and a continuous service temperature far beyond the thermoplastic range. It is also the most expensive of the five by a wide margin, and the least flexible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-a-ptfe-hose-is-actually-made-of\">What a PTFE Hose Is Actually Made Of<\/h3>\n\n\n\n<p>A PTFE hose is a composite rather than a single tube of plastic. The construction is a thin PTFE liner, usually a smooth bore or a convoluted form, covered by a stainless steel wire braid that carries the pressure and protects the liner from abrasion. The braid is structural: the liner alone holds very little pressure, and the assembly rating comes from the combination of the two.<\/p>\n\n\n\n<p>That construction is why PTFE hose is supplied as a finished assembly rather than as a length to be clamped. The liner deforms under compression, so a worm-drive clamp cannot retain or seal it, and the end fitting is crimped or swaged onto the liner and braid together.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"the-temperature-and-pressure-envelope-of-a-ptfe-hose\">The Temperature and Pressure Envelope of a PTFE Hose<\/h3>\n\n\n\n<p>The braided PTFE construction used for hydraulic and chemical service is specified under SAE 100R14, a braided PTFE style in the 100R series of SAE J517, Hydraulic Hose, using a PTFE tube with a stainless steel wire braid. The pressure rating falls as bore rises, so a small-bore and a large-bore assembly of the same style do not share a rating. The temperature band is assigned from the assembly grade rather than read for the style.<\/p>\n\n\n\n<p>Where the service needs a tighter bend radius than a smooth-bore liner allows, a corrugated construction is used. Corrugated metal hose and hose assemblies are specified under ISO 10380, which covers the design, manufacture and testing of the assembly rather than of the liner alone.<\/p>\n\n\n\n<p>The specification points that decide a PTFE hose order are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The liner form, smooth bore or convoluted, since it sets the bend radius and the flow path<\/li>\n\n\n\n<li>The braid, single or double, and the alloy, because the braid sets the pressure rating<\/li>\n\n\n\n<li>The end fitting and the hose assembly as a tested unit rather than as separate items<\/li>\n\n\n\n<li>The fluid, because permeation through a PTFE wall is low but not zero for some gases and vapours<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"when-is-ptfe-the-wrong-answer\">When Is PTFE the Wrong Answer?<\/h3>\n\n\n\n<p>PTFE is not a general-purpose hose at any price point. It is a poor choice where flexibility matters, because the liner and braid combination is stiffer than an elastomer hose of the same bore and will not tolerate repeated flexing at a tight radius unless the liner is convoluted. It is a poor choice where cost per metre dominates, because the material cost sits an order of magnitude above PVC or rubber. And it is a poor choice where a clamped connection is required, because the liner cannot be secured by a clamp.<\/p>\n\n\n\n<p>The material also has one specific weakness worth stating. PTFE cold-flows under sustained compression, so a joint that relies on a compressed liner to seal will lose preload over time, which is why the fitting design matters as much as the liner. For food, pharmaceutical and high-purity service the liner is normally declared against a perfluorocarbon food-contact specification rather than against a general hose standard.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram.jpg\" alt=\"Cutaway diagram of a braided PTFE hose showing the thin PTFE liner, the single stainless steel wire braid carrying the pressure, and a crimped end fitting\" class=\"wp-image-5577\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/ptfe-hose-braid-liner-construction-diagram-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 3.

Temperature comes first, hose chemical compatibility second, pressure third, then abrasion and flex life, and finally the contact approvals that apply when the fluid is food or drinking water.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"temperature-the-first-screen-and-the-one-most-often-skipped\">Temperature: the First Screen, and the One Most Often Skipped<\/h3>\n\n\n\n<p>The hose temperature rating is the first figure to read and the one that removes whole families from consideration. It sorts the types of hoses faster than any other property, because it is a band rather than a maximum. The bottom of the band decides whether the hose survives a cold start, and the top decides whether it survives a hot process.<\/p>\n\n\n\n<p>The table below lists the temperature range each material carries in normal service, the duty that most often exceeds it, and the material that replaces it in that duty.<\/p>\n\n\n\n<p>Hose temperature rating by material, the duty that commonly exceeds the range that applies, and the material that is correct in its place.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th scope=\"col\">Material<\/th><th scope=\"col\">Temperature range that applies<\/th><th scope=\"col\">Duty that commonly exceeds it<\/th><th scope=\"col\">What to specify instead<\/th><\/tr><\/thead><tbody><tr><td>Rubber (natural rubber, SBR)<\/td><td>\u221225 \u00b0C to +70 \u00b0C for general-purpose water hose under ISO 1403<\/td><td>Water above 70 \u00b0C, or permanent outdoor exposure to sunlight and ozone<\/td><td>An EPDM hose for hot water, and a hose with a weather-resistant cover for outdoor routing<\/td><\/tr><tr><td>EPDM<\/td><td>\u221240 \u00b0C to +135 \u00b0C typical for EPDM coolant hose; SAE J20 sets a high-temperature class above 125 \u00b0C<\/td><td>Saturated steam, or a hot process above 135 \u00b0C<\/td><td>A steam hose declared for saturated steam duty, or a braided PTFE assembly above the steam range<\/td><\/tr><tr><td>PVC<\/td><td>\u221210 \u00b0C to +60 \u00b0C as commonly declared for PVC water grades<\/td><td>Hot water, steam, or a cold start below \u221210 \u00b0C<\/td><td>An EPDM or rubber hose for hot water, and a polyurethane hose where cold flexibility is the requirement<\/td><\/tr><tr><td>Poliuretano<\/td><td>\u221210 \u00b0C to +60 \u00b0C for compressed-air hose under ISO 5774<\/td><td>Hot water, steam, and wet abrasive duty at elevated temperature<\/td><td>An EPDM hose for hot water, and a rubber hose for wet abrasive duty<\/td><\/tr><tr><td>PTFE<\/td><td>Above the +135 \u00b0C EPDM ceiling, the highest of the other four; the exact limit is set by the assembly grade<\/td><td>A duty above every polymer family in this guide<\/td><td>A corrugated metal hose assembly rather than a polymer hose<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Two temperatures have to be measured rather than assumed. The first is the fluid temperature at the hose, which is often higher than the temperature at the tank or the pump. The second is the ambient temperature around the hose, including radiant heat from adjacent equipment, and the figure that governs the rating is whichever of the two is higher.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"chemical-compatibility-test-the-compound-do-not-assume-it\">Chemical Compatibility: Test the Compound, Do Not Assume It<\/h3>\n\n\n\n<p>Hose chemical compatibility is not a property of the material name alone. It depends on the base polymer, the plasticiser or the cure system, the concentration of the fluid, the temperature, and the duration of contact. That is why two hoses sold under the same material name can behave differently in the same line.<\/p>\n\n\n\n<p>Rubber compounds are qualified for fluid resistance by immersion testing. The standard method is ASTM D471, which measures the change in tensile strength, elongation and volume after a specimen has been soaked in the test fluid for a defined time at a defined temperature. The reference oil used for the oil-resistance evaluation is IRM 903. A compound that passes is declared resistant to that fluid at that concentration and that temperature, and the declaration does not extend to a hotter line or a stronger concentration.<\/p>\n\n\n\n<p>For chemical transfer duty the hose is specified against a chemical hose document rather than against a water or air specification. EN 12115 covers two hose types, D and SD, across \u221220 \u00b0C to +65 \u00b0C at a working pressure of up to 10 bar. A fluids-immersion test is incorporated by reference to ISO 1817 rather than as a blanket compatibility certification.<\/p>\n\n\n\n<p>The verification sequence that avoids a wrong answer is short:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Identify the fluid by its exact chemical name rather than by its trade name or its end use<\/li>\n\n\n\n<li>Record the maximum concentration and the maximum temperature at the hose as separate figures<\/li>\n\n\n\n<li>Check the compound&#8217;s immersion test data at that concentration and that temperature<\/li>\n\n\n\n<li>Establish whether the duty is continuous immersion or intermittent contact<\/li>\n\n\n\n<li>Confirm the cover as well as the tube, because a failed cover lets fluid reach the reinforcement<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pressure-the-reinforcement-sets-the-rating-the-tube-does-not\">Pressure: the Reinforcement Sets the Rating, the Tube Does Not<\/h3>\n\n\n\n<p>The hose working pressure belongs to the construction rather than to the polymer. A tube and a cover hold almost nothing on their own, because the textile braid, the wire braid or the spiral layer carries the hoop load. The same EPDM tube can be built into a 10 bar hose or a 200 bar hose depending on what surrounds it.<\/p>\n\n\n\n<p>A material can be right for the fluid and right for the temperature and still be wrong for the pressure. The correction is a heavier reinforcement rather than a different polymer. The reinforcement can also set the temperature ceiling in some designs, because a textile braid has its own thermal limit that may sit below the tube&#8217;s limit. Both facts mean the hose working pressure is a property of the assembly rather than of the material name on the order.<\/p>\n\n\n\n<p>The four pressure figures that belong in any hose specification are these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The maximum working pressure at the operating temperature rather than at ambient<\/li>\n\n\n\n<li>The minimum burst pressure, which is normally a multiple of the working pressure<\/li>\n\n\n\n<li>The relief valve setting of the system, which is the true maximum the line can reach<\/li>\n\n\n\n<li>The pressure spikes generated when a valve closes or a pump starts cold<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"abrasion-ozone-and-flex-life\">Abrasion, Ozone and Flex Life<\/h3>\n\n\n\n<p>Abrasion resistance and weather resistance are cover properties, and they are why two hoses with identical tubes can have very different service lives. Rubber covers tolerate dragged and rough-ground routing, polyurethane covers resist cutting and gouging, and a thin PVC cover is the least abrasion-resistant of the three.<\/p>\n\n\n\n<p>Ozone resistance is a test rather than an assumption. ISO 7326 covers the assessment of ozone resistance of rubber and plastics hoses under static conditions, which matters for any hose stored or routed where ozone from electrical equipment or sunlight is present. Flex life is measured rather than estimated: ISO 10619-1 and ISO 10619-2 cover the measurement of flexibility and stiffness of rubber and plastics hoses and tubing, and that measurement is the basis of a published minimum bend radius.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"food-and-drinking-water-contact-a-separate-approval-from-the-material\">Food and Drinking-Water Contact: a Separate Approval From the Material<\/h3>\n\n\n\n<p>Food and drinking-water duty adds a compliance requirement on top of the material choice, and it is not satisfied by the base polymer alone. For rubber compounds the relevant document is FDA 21 CFR 177.2600, which lists permitted base elastomers and permitted compounding ingredients for rubber articles intended for repeated use in contact with food, and which limits how much material may migrate out. For perfluorocarbon resins such as PTFE, the parallel document is FDA 21 CFR 177.1550.<\/p>\n\n\n\n<p>Equipment-side approvals are separate again. NSF\/ANSI 51 covers materials for food equipment, and NSF\/ANSI\/CAN 61 covers components in contact with drinking water. The two are not interchangeable, so a hose carrying a food-contact declaration is not automatically acceptable on a potable water line. The general-purpose rubber water hose specification also excludes potable water from its scope, which means a hose offered for drinking water has to be declared against a drinking-water standard rather than against the water hose standard. A potable water hose is identified by that approval rather than by its material.<\/p>\n\n\n\n<p>For drinking water and food transfer the shortlist is normally EPDM for hot-water and washdown duty, a food-grade rubber compound where repeated flexing matters, and PTFE where chemical resistance and high-purity contact are required. Our <a href=\"https:\/\/www.henghuahose.com\/es\/product\/food-discharge-hose-150psi\/\" target=\"_blank\" rel=\"noopener\">food discharge hose<\/a> is built on that basis and supplied with the compound documentation the food-contact declaration depends on.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"property-matrix-the-five-materials-side-by-side\">Property Matrix: the Five Materials Side by Side<\/h3>\n\n\n\n<p>The matrix below puts the types of flexible hose materials in this guide on the same six properties.

The starting point is the marking on the hose, because an unmarked hose cannot be checked against anything.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Read the marking on the cover and identify the standard and any designation printed with it<\/li>\n\n\n\n<li>Look up the stated temperature range and pressure class in that standard for the bore you need<\/li>\n\n\n\n<li>Measure the worst-case fluid temperature and the ambient temperature at the hose, and take the higher figure<\/li>\n\n\n\n<li>Confirm the relief valve setting, and treat that as the working pressure the hose has to hold<\/li>\n\n\n\n<li>Confirm hose chemical compatibility for the exact fluid, concentration and temperature, and confirm the end connection suits the construction<\/li>\n<\/ul>\n\n\n\n<p>The order of the five checks follows the cost of being wrong. A marking check takes seconds and rules out the hoses of unknown origin that generate most failures. A temperature check comes next because it eliminates whole material families. The fluid and pressure checks come last because they need measured data rather than a look at the hose. Run in this order, the check settles which of the types of flexible hose materials fits the line before any quotation is compared.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-each-material-looks-like-when-it-is-the-wrong-choice\">What Each Material Looks Like When It Is the Wrong Choice<\/h2>\n\n\n\n<p>The failure pattern identifies a mismatch faster than any test, because each of the five families fails in a characteristic way. Reading the pattern is the shortest route from a failed hose back to the correct specification, and it separates the types of hoses as well as the materials.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A swollen, softened tube that has closed down the bore indicates a chemical mismatch: natural rubber in oil, EPDM in fuel, or PVC against a solvent<\/li>\n\n\n\n<li>A hardened cover with surface cracking indicates heat ageing or ozone exposure, and a compound that belongs in a hotter or better-protected class<\/li>\n\n\n\n<li>A flattened or collapsed hose on the inlet side of a pump indicates suction duty without a helix-wire construction<\/li>\n\n\n\n<li>A ballooned wall that splits at a bend indicates a thermoplastic hose run above its temperature range<\/li>\n\n\n\n<li>A permanent kink at one point on an older hose indicates plasticiser loss, and a thermoplastic hose past its useful flexibility<\/li>\n\n\n\n<li>A liner separated from the braid, or deformed at the fitting, indicates a PTFE assembly built with the wrong end connection<\/li>\n<\/ul>\n\n\n\n<p>Two of the failure patterns deserve separating from the rest. A swollen tube is a fluid problem, and it cannot be solved by buying a heavier hose of the same compound. A burst or a split is a temperature or pressure problem, and it usually can be solved by a heavier reinforcement or a different compound. Deciding which of the two you are looking at determines the fix.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq\">Preguntas frecuentes<\/h2>\n\n\n\n<p><strong>What are the types of flexible hose materials?<\/strong><\/p>\n\n\n\n<p>The five families that cover almost all flexible hose demand are rubber (natural rubber and SBR), EPDM, PVC, polyurethane and PTFE. Rubber, EPDM and other vulcanised elastomers are governed by the rubber hose standards, and PVC, polyurethane and PTFE are thermoplastics governed by separate plastics hose standards. A sixth group, silicone, is a separate elastomer family with its own temperature class and is specified from its own manufacturer data rather than from the standards listed here.<\/p>\n\n\n\n<p><strong>Which hose material is best for water?<\/strong><\/p>\n\n\n\n<p>For ambient-temperature water, a rubber hose is the strongest general-purpose answer, because the general-purpose rubber water hose specification covers \u221225 \u00b0C to +70 \u00b0C and pressure classes up to 25 bar. For hot water and washdown duty above the rubber range, EPDM is the correct family. PVC is the lowest-cost answer for ambient water where light weight and low pressure are acceptable. There is no single best hose material for water; the temperature of the water and the pressure class decide between the three.<\/p>\n\n\n\n<p><strong>Is EPDM better than PVC for a hose?<\/strong><\/p>\n\n\n\n<p>They are not competing for the same duty. EPDM covers roughly \u221240 \u00b0C to +135 \u00b0C in coolant service and resists ozone, sunlight and hot water, while a general-purpose PVC water hose is declared across \u221210 \u00b0C to +60 \u00b0C. EPDM is the better choice for hot water, outdoor routing and coolant systems, and PVC is the better choice where lowest cost per metre, light weight and a clear wall matter more than temperature range.<\/p>\n\n\n\n<p><strong>What is the difference between a rubber hose and a thermoplastic hose?<\/strong><\/p>\n\n\n\n<p>Rubber hose is vulcanised, so its polymer chains are chemically crosslinked and the tube cannot be melted or re-formed. Thermoplastic hose is extruded and cooled, so it softens progressively as it warms and re-hardens as it cools. The practical consequences are that rubber holds its elasticity down to a lower temperature and resists kinking better, while a thermoplastic hose can be heat-formed and welded but must be de-rated as the temperature rises. The distinction runs through all types of hoses, from a garden hose to a wire-braided hydraulic assembly.<\/p>\n\n\n\n<p><strong>How durable is the hose material?<\/strong><\/p>\n\n\n\n<p>Durability is set by the cover and the duty rather than by the polymer name alone. Abrasion life depends on the cover compound, weather life depends on resistance to ozone and ultraviolet light, and chemical life depends on the tube&#8217;s resistance to the specific fluid at its actual concentration and temperature. Two hoses with the same tube can have service lives that differ by years if one is dragged over concrete and the other is fixed in a rack.<\/p>\n\n\n\n<p><strong>Can a polyurethane hose be used for hot water?<\/strong><\/p>\n\n\n\n<p>No, and this is one of the more common specification errors. Polyurethane is degraded by sustained contact with hot water, and the failure develops from the inside as the tube softens, becomes tacky and then loses wall strength. An EPDM hose is the correct material for hot water at the same bore, and polyurethane is best kept for dry, abrasive duty such as pneumatic tool hose.<\/p>\n\n\n\n<p><strong>Is a PTFE hose worth the cost?<\/strong><\/p>\n\n\n\n<p>It is worth the cost where the fluid would destroy every cheaper material, or where the service temperature is above the range of an EPDM hose. It is not worth the cost for water, air or ordinary hot-water duty, where a rubber or EPDM hose does the job at a fraction of the price. A braided PTFE assembly is also stiffer than an elastomer hose of the same bore, so it needs a larger bend radius and crimped end fittings.<\/p>\n\n\n\n<p><strong>What are hoses made of?<\/strong><\/p>\n\n\n\n<p>A hose is a composite of at least three parts. The inner tube carries the fluid and sets the temperature and chemical limits. The reinforcement, whether textile braid, wire braid or helix wire, carries the pressure. The outer cover protects the reinforcement from abrasion, weather and ozone. The tube polymer gives the material its name, but the reinforcement is what sets the pressure rating.<\/p>\n\n\n\n<p><strong>Which hose material is safe for drinking water?<\/strong><\/p>\n\n\n\n<p>The material has to be declared against a drinking-water standard rather than a general water hose standard, because the general-purpose rubber water hose specification excludes potable water from its scope. EPDM and food-grade rubber compounds are the usual choice, and the compound is normally documented against FDA 21 CFR 177.2600 for food contact and against a drinking-water approval such as NSF\/ANSI\/CAN 61 for potable water service. Any potable water hose therefore carries an approval number rather than only a material name.<\/p>\n\n\n\n<p><strong>What is a hose temperature rating and why does it matter?<\/strong><\/p>\n\n\n\n<p>A hose temperature rating is the band within which the hose is declared to operate, and both ends of the band matter. The upper figure decides whether the tube softens or ages prematurely, and the lower figure decides whether the hose stays flexible enough to route and uncoil without cracking. The rating applies to the higher of the fluid temperature and the ambient temperature at the hose, including radiant heat from nearby equipment.<\/p>\n\n\n\n<p><strong>Do I need to test hose chemical compatibility, or can I trust the material name?<\/strong><\/p>\n\n\n\n<p>The material name is not enough, because two hoses sold under the same name can differ in plasticiser, cure system or filler. Compatibility is established by immersion testing, which is run to ASTM D471 for rubber compounds and measures the change in tensile strength, elongation and volume after exposure to the fluid. Ask for the test data at your concentration and temperature, and treat a declaration made at a lower temperature as evidence about that temperature and nothing more.<\/p>\n\n\n\n<p><strong>Which hose material should I choose for compressed air?<\/strong><\/p>\n\n\n\n<p>Polyurethane is the usual choice for pneumatic tool hose because of its abrasion resistance and cold flexibility, within a stated range of \u221210 \u00b0C to +60 \u00b0C. Check the pressure at the working temperature rather than at ambient, because the compressed-air hose standard rates light service at 7 bar at 23 \u00b0C and only 4.5 bar at 60 \u00b0C. Where the air is hot or the ambient is beyond the range, a rubber air hose is the more robust answer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"choosing-the-right-hose-material-for-your-application\">Choosing the Right Hose Material for Your Application<\/h2>\n\n\n\n<p>The types of flexible hose materials in this guide are not ranked against each other, because each one is the correct answer inside its own range and the wrong answer outside it. The decision reduces to three measured figures \u2014 the fluid, the temperature at the hose, and the pressure the line can actually reach \u2014 applied in that order to the family that covers all three. Where a material is right for the fluid and wrong for the pressure, the fix is a heavier reinforcement or a different assembly, not a different polymer.<\/p>\n\n\n\n<p>HENGHUA manufactures reinforced rubber and thermoplastic hose for water, air, steam, chemical and food service, supplying equipment builders, distributors, plant operators and contractors. The range covers the material families described above, from general-purpose rubber water discharge and suction hose through EPDM steam hose to food and chemical hose built with compounds documented for contact service.<\/p>\n\n\n\n<p>Production is organised around the four properties that decide whether a hose survives: the tube compound, the reinforcement, the cover and the end connection. Extrusion, reinforcement, covering and assembly are handled in house, which means the temperature and pressure figures published for a hose can be traced back to the batch that produced it rather than to a generic catalogue value.<\/p>\n\n\n\n<p>The specification support we provide before an order is straightforward and free of obligation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material selection and hose chemical compatibility checks against your fluid, temperature and pressure figures rather than against a material name<\/li>\n\n\n\n<li>Standard citations for the hose we quote, so your own inspection team can verify the declared range<\/li>\n\n\n\n<li>Sample lengths for trial on your equipment before a production order<\/li>\n\n\n\n<li>Custom bore, length, colour, cover and end connections matched to the installation<\/li>\n\n\n\n<li>OEM and private-label programmes for distributors and brands<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"which-material-should-i-specify-if-one-hose-has-to-handle-hot-water-and-a-cleaning-chemical\">Which material should I specify if one hose has to handle hot water and a cleaning chemical?<\/h3>\n\n\n\n<p>Treat the two duties as two hoses unless a single hose is genuinely declared for both. A cleaning chemical at temperature is a chemical hose duty, and it needs a compound with documented resistance at that concentration and temperature; hot water alone is an EPDM duty. Specifying one material for both usually means the chemical resistance is assumed rather than declared, which is where chemical hose failures begin. Where the two duties are unavoidable on one line, a braided PTFE assembly with crimped fittings is the material that covers both, at the cost of a larger bend radius and a much higher price per metre.<\/p>\n\n\n\n<p>If you are selecting a hose material for a new line, or replacing one that failed early, send us five figures. We need the fluid, the maximum working pressure including the relief setting, the worst-case temperature at the hose, the bore size, and whether the line runs under suction. Our engineering team will confirm which of the types of flexible hose materials fits the duty, and which reinforcement it needs. <a href=\"https:\/\/www.henghuahose.com\/es\/contact\/\" target=\"_blank\" rel=\"noopener\">Contact our engineering team<\/a> with those figures, or review the wider <a href=\"https:\/\/www.henghuahose.com\/es\/flexible-hose-materials-guide\/\" target=\"_blank\" rel=\"noopener\">flexible hose materials guide<\/a> for the ten-material selection matrix.<\/p>\n\n\n\n<p>For related reading, the comparison of PVC and rubber garden hose applies the same reasoning to outdoor water hose. The rubber versus PVC air hose guide covers the compressed-air case in detail, and the <a href=\"https:\/\/www.henghuahose.com\/es\/hydraulic-hose-fluid-compatibility-chart-nbr-vs-epdm-vs-fkm-inner-tube-selection-guide\/\" target=\"_blank\" rel=\"noopener\">inner tube compatibility chart<\/a> explains how NBR, EPDM and FKM tubes differ against specific fluids.<\/p>\n\n\n\n<p>Ratings, temperature limits and standard references in this guide are reviewed on a quarterly cycle. The figures taken from ISO 1403, ISO 4641 and ISO 5774 were last checked on 20 September 2026 against the current published editions. The service temperature ranges shown for PVC, coolant and PTFE hose are practice-based figures, and should be confirmed on the supplier&#8217;s hose declaration.<\/p>\n\n\n\n<p><strong>About the author:<\/strong> Written by the HENGHUA Engineering Team \u2014 hose application engineers and assembly specialists supporting material selection, coupling and pressure testing for industrial, water, steam, chemical and food-grade hose customers.
