In practice the 100R1 to 100R2 line sits near 2,000 psi, and the 100R2 vs 100R16 line is decided by the tightest radius the routing allows.

On a European drawing, the same choice is written as a 2SN vs 2SC question, with the pressure tables expressed in bar rather than psi. 100R1 corresponds to EN 853 1SN and ISO 1436 Type 1SN. 100R2 corresponds to EN 853 2SN and ISO 1436 Type 2SN. 100R16 corresponds to EN 857 Type 2SC and ISO 11237 Type R16.<\/p>\n\n\n\n<p>Table 2.

The same 3\/8 inch bore is published at 15.7 MPa (2,280 psi) on the SAE 100R1AT table and 18 MPa (2,610 psi) on the EN 853 1SN table, because each figure belongs to the specification the hose was tested against. A cross-reference tells you which codes describe the same construction; it does not tell you that the two codes publish the same number.<\/p>\n\n\n\n<p>Because the two-braid construction is what separates 100R2 and 100R16 from 100R1, the pressure step from 100R1 to 100R2 is the largest single jump in the medium-pressure family \u2014 about 1.72 to 1.98 times the working pressure up to 3\/4 inch, 1.97 times at 1 inch and 2.42 times at 1-1\/4 inch, where the two published tables diverge most. It is not a doubling, because the second braid layer also changes how the first layer is loaded. The step is smallest exactly where most mobile machinery is specified, and that is why the 100R2 decision is usually made on the bore and the routing rather than on the pressure alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-the-at-suffix-means-in-100r1at-and-100r2at\">What the &#8220;AT&#8221; Suffix Means in 100R1AT and 100R2AT<\/h3>\n\n\n\n<p>The suffix on a hose marking tells you which assembly method the hose was built for, not what pressure it holds. &#8220;AT&#8221; indicates a no-skive hose: the cover is thin enough that a crimp ferrule can be pressed directly over it, without machining the cover back to expose the wire braid. The older Type A design required skiving and no-skive fittings to be chosen separately, which is why second-hand literature sometimes quotes different dimensions for &#8220;100R1&#8221; and &#8220;100R1AT&#8221; of the same size.<\/p>\n\n\n\n<p>A 100R1AT and a 100R1 Type A hold the same pressure class, but the AT version is lighter and has a smaller outside diameter \u2014 and the two are not interchangeable on the same ferrule without checking the crimp specification. A marking of 100R2AT and a table headed SAE J517 100R2AT describe the same construction class: the pressure column you design to is the one published for the exact hose in your hand, while the AT \/ Type A distinction affects cover, outside diameter and crimp specification rather than the pressure class.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-100r16-sits-the-compact-two-braid-family\">Where 100R16 Sits: The Compact Two-Braid Family<\/h3>\n\n\n\n<p>100R16 was written for the problem 100R2 cannot solve: a machine that needs 4,000 psi in a hose run that has no room for a 100R2&#8217;s outside diameter or bend radius. The construction is the same two-braid architecture squeezed into a tighter package, and the result is a compact hydraulic hose whose bending radius is close to half that of a 100R2 of the same nominal size. That compression is why the SAE 100R16 pressure rating is published per size rather than as a single figure, and why the compact hydraulic hose is normally specified from the routing drawing rather than from the pressure line on the schematic.<\/p>\n\n\n\n<p>The trade-offs are deliberate: the cover is thinner, the available size range stops around 1 inch to 1-1\/4 inch, and the compact build has less cover material to absorb abrasion.<\/p>\n\n\n\n<p>100R17 is its sibling \u2014 the single-braid companion to 100R16, a compact one-layer construction rated a flat 3,000 psi in every size rather than from a size-by-size table, published as EN 857 1SC and ISO 11237 R17. A 100R16 vs 100R17 comparison therefore turns on one question: does the circuit need the highest available pressure in a tight space (100R16), or one predictable rating across every size (100R17)? Both are manufactured as standard production lines, and the SAE 100R17 compact hose and the <a href=\"https:\/\/www.henghuahose.com\/de\/product\/en-857-2sc-hydraulic-hose\/\" target=\"_blank\" rel=\"noopener\">EN 857 2SC compact hose<\/a> that corresponds to 100R16 share the no-skive assembly approach.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"working-pressure-100r1-vs-100r2-vs-100r16-by-dash-size\">Working Pressure: 100R1 vs 100R2 vs 100R16 by Dash Size<\/h2>\n\n\n\n<p>Working pressure is the number of the comparison that decides most jobs, and it is a per-size value, not a property of the specification alone. Read it from a hydraulic hose working pressure chart at your dash size rather than from a family figure, because every specification in this family is published size by size. The table below is that hydraulic hose working pressure chart for the three specifications across the sizes most often specified in mobile and industrial hydraulics: the SAE 100R16 pressure rating at -6 (3\/8 inch) is 33 MPa \/ 4,785 psi, against 27.6 MPa \/ 4,000 psi for the 100R2AT in the same bore. Values are working pressure, not burst pressure; the minimum burst pressure for all three is specified at four times the maximum working pressure (SAE J517 \/ EN 853 \/ EN 857).<\/p>\n\n\n\n<p>SAE J517 100R2AT and EN 853 2SN are the SAE and European codes for the same two-wire braid construction, but the two standards publish different working pressures at some dash sizes: this table follows the SAE J517 100R2AT column, and the EN 853 2SN values for the same dash sizes run higher. Confirm the figure for the exact dash size and standard on the datasheet before ordering, because a hose built to one code is not interchangeable with a hose built to the other at every size.<\/p>\n\n\n\n<p>Table 3.

That widening step is the number to read before you substitute one construction for the other by size alone; the one-braid side of it is worked through in detail in our 100R1 vs 100R2 construction comparison. Second, 100R16 matches or exceeds 100R2 in every size where both exist, and the gap widens in the larger sizes because the compact construction is built to the European 2SC table rather than the 100R2 table. Third, no hose in this family is rated at a single pressure across all sizes unless the specification says so \u2014 only 100R17 and 100R18 behave that way. The full hydraulic hose working pressure chart, including proof and minimum burst pressures for every dash size, is published on the SAE 100R1 single wire braid hose and <a href=\"https:\/\/www.henghuahose.com\/de\/product\/sae-100-r2-hydraulic-hose\/\" target=\"_blank\" rel=\"noopener\">SAE 100R2 double wire braid hose<\/a> product pages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-the-100r1-vs-100r2-pressure-gap-is-not-exactly-double\">Why the 100R1 vs 100R2 Pressure Gap Is Not Exactly Double<\/h3>\n\n\n\n<p>Two wire layers raise the working pressure by roughly 1.72 to 1.98 times across the -4 to -12 range, rather than doubling it, because the two layers do not carry identical loads. The inner braid sits close to a tube that expands slightly under pressure, while the outer braid sits on top of the first and sees a different hoop stress pattern. What the second layer mainly buys is resistance to impulse fatigue \u2014 repeated pressure spikes \u2014 rather than a clean multiple of steady-state pressure. In test benches, a single-braid 100R1 hose that passes a steady pressure test will still degrade faster than a 100R2 on a circuit with frequent spikes, which is why the specification choice for shock-loaded circuits is made on impulse life rather than on the working-pressure number alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-rating-falls-as-bore-grows\">How Rating Falls as Bore Grows<\/h3>\n\n\n\n<p>Working pressure falls steeply as bore grows, but not in proportion to it: on the tables here it drops about 60 percent when the bore quadruples \u2014 a 1\/4-inch 100R2AT is rated 5,000 psi and a 1-inch 100R2AT 2,000 psi, for four times the bore and sixteen times the flow area at the same fluid velocity. The reason is wall stress: hoop stress rises with diameter for the same pressure and the same reinforcement thickness, so the same construction holds less pressure as it grows \u2014 a fall of 60 percent, not the 75 percent that a strictly proportional rule would predict. The practical consequence is that a hose size is never chosen from flow alone. A 1-inch line that needs 3,000 psi is one of the cases where a spiral hose beats a two-wire braid hose, because the braided construction has already run out of pressure at that diameter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"outside-diameter-bend-radius-and-weight-where-100r16-wins\">Outside Diameter, Bend Radius and Weight: Where 100R16 Wins<\/h2>\n\n\n\n<p>Geometry, not pressure, is the reason 100R16 exists: the 100R2 vs 100R16 decision turns on bend radius and outside diameter (Table 4), not on working pressure (Table 3). In the same dash size, a compact hydraulic hose such as 100R16 is built to a smaller outside diameter, bends to about half the radius, and weighs less than the equivalent 100R2.

Largest dash size each construction allows for a given available bend radius, read from Table 4 (100R16 values are half the 100R1 \/ 100R2 values at every size).<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th scope=\"col\">Tightest radius the routing allows<\/th><th scope=\"col\">Largest 100R1 \/ 100R2 dash size<\/th><th scope=\"col\">Largest 100R16 dash size<\/th><th scope=\"col\">What it means<\/th><\/tr><\/thead><tbody><tr><td>50 mm<\/td><td>None \u2014 the smallest 100R1 \/ 100R2 radius is 100 mm at -4<\/td><td>-4 (50 mm)<\/td><td>Only the compact construction can be routed here at all<\/td><\/tr><tr><td>90 mm<\/td><td>None<\/td><td>-8 (90 mm)<\/td><td>A 1\/2 inch pressure line is still available, in the compact build<\/td><\/tr><tr><td>100 mm<\/td><td>-4 (100 mm)<\/td><td>-8 (90 mm)<\/td><td>Both constructions exist, but only in their smallest sizes<\/td><\/tr><tr><td>150 mm<\/td><td>-6 (125 mm)<\/td><td>-16 (150 mm)<\/td><td>The compact hose now gives two dash sizes of extra bore<\/td><\/tr><tr><td>180 mm<\/td><td>-8 (180 mm)<\/td><td>-16 (150 mm, the largest size in this table)<\/td><td>The standard hose has caught up on bore<\/td><\/tr><tr><td>240 mm and above<\/td><td>-12 or larger (240 mm)<\/td><td>-16 (largest size in this table)<\/td><td>Bend radius no longer decides; pressure, flow and abrasion do<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The rule behind the table is the same one the sizing step uses: if the radius the routing allows is tighter than the bend radius published for the standard two-braid hose at the dash size the flow requires, the compact 100R16 is the answer; if it is not, the standard two-braid hose is the cheaper choice in the same bore. Whatever the routing decides, the SAE 100R16 pressure rating at that dash size still has to cover the circuit pressure \u2014 which is why the two readings are always taken together.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-a-tighter-bend-radius-matters-more-than-it-sounds\">Why a Tighter Bend Radius Matters More Than It Sounds<\/h3>\n\n\n\n<p>Bend radius determines how much hose a machine needs and how long it lasts. A hose that must reach a 125 mm radius on a moving boom needs extra length and extra routing brackets to keep the bend from being forced; the same circuit laid out with a 65 mm minimum radius can take a shorter, straighter path, which reduces hose length, reduces the number of clamps, and lowers the chance of the hose rubbing against a machine member. The flow and service-life effects of that geometry are covered in more detail in our guide to hydraulic hose bend radius. In our own assembly shop, the most common routing correction we make on a supplied drawing is a hose that has been sized for pressure but not for the bend radius at the fitting \u2014 the hose fits the port and then kinks 200 mm behind it, and the customer sees a failure six weeks later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-a-100r2-will-not-fit-at-all\">Where a 100R2 Will Not Fit At All<\/h3>\n\n\n\n<p>There are installations where the choice is not a preference but a physical constraint: retract cylinders inside a boom, steering lines routed through a mast or a pivot, hydraulic hose in a cab or turret with no clearance, and any line that has to pass through a bulkhead with fixed hole diameters. In those cases an SAE 100R2 cannot be routed without exceeding its minimum bend radius, and forcing the bend is exactly the failure mode the compact specification was written to prevent. This is also the case where a hose is replaced by nominal size only: a 100R2 and a 100R16 of the same dash size look similar on a shelf, but their ferrules and crimp diameters are different.<\/p>\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\/sae-100r1-100r2-100r16-side-by-side-cutaway.jpg\" alt=\"Cutaway comparison of SAE 100R1 single wire braid, SAE 100R2 double wire braid and SAE 100R16 compact double wire braid hydraulic hose showing tube, reinforcement and cover layers\" class=\"wp-image-5395\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r1-100r2-100r16-side-by-side-cutaway.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r1-100r2-100r16-side-by-side-cutaway-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r1-100r2-100r16-side-by-side-cutaway-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r1-100r2-100r16-side-by-side-cutaway-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r1-100r2-100r16-side-by-side-cutaway-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 1. 100R1 (single braid), 100R2 (double braid) and 100R16 (compact double braid) cut side by side.

Differences appear at the edges of that range and in what the cover can survive.<\/p>\n\n\n\n<p>Table 7.

The first is water-based fluid: when a machine runs on a water-glycol fluid, the continuous temperature limit drops well below the rubber&#8217;s nominal 100\u00b0C \u2014 around +70\u00b0C in most published tables \u2014 and a hose that is fine on mineral oil will age prematurely if it is left at the top of its range on a water-based fluid. The second is cover thickness. The thin AT cover and the compact 100R16 cover both give up material for flexibility, and the place that material is missing is exactly the place a hose rubs against a machine. Where a hose runs through a wear zone, a protective sleeve or guard is cheaper than a specification upgrade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-100r16-does-not-solve\">What 100R16 Does Not Solve<\/h2>\n\n\n\n<p>100R16 is often described as a straight upgrade, and that is only true for the problem it was designed for. Four limits matter before you standardize on it.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Size range.<\/strong> The compact family stops around 1 inch to 1-1\/4 inch, which is the same limit that applies to the 2SN vs 2SC equivalents in the European tables. If the line is a 1-1\/2 inch or 2 inch pressure line, 100R16 does not exist in your size and 100R2 or a spiral hose is the answer.<\/li>\n\n\n\n<li><strong>Abrasion exposure.<\/strong> A thinner cover wears through faster on rock, concrete and steel edges. On a mining or demolition machine, the correct combination is often a compact hose plus a protective sleeve, not a compact hose alone.<\/li>\n\n\n\n<li><strong>Fitting and crimp compatibility.<\/strong> 100R16 needs a ferrule and crimp diameter matched to the compact build. A ferrule sized for 100R2 will not produce a correct crimp on a 100R16, even in the same dash size, and a mismatch shows up as a pull-off or a leak at the crimp rather than as a burst.<\/li>\n\n\n\n<li><strong>Availability in every size and construction.<\/strong> 100R2 is stocked by virtually every distributor in every dash size. 100R16 is stocked in the sizes that sell, which is usually -4 through -12. If your maintenance plan depends on same-day hose, that stocking difference is a real constraint on a standard-build machine.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"fittings-ferrules-and-crimp-specs-are-not-interchangeable\">Fittings, Ferrules and Crimp Specs Are Not Interchangeable<\/h3>\n\n\n\n<p>The common failure we are asked to diagnose is a compact hose assembled with the wrong ferrule. The hose is marked 100R16, the crimper is set to a 100R2 programme of the same dash size, and the assembly passes a visual inspection because the outside diameters are close. The crimp is then either under-compressed \u2014 the hose pulls out of the ferrule under load \u2014 or over-compressed, which cuts the outer braid and leaves a hose that bursts below its rated pressure. The rule is simple: crimp to the coupling manufacturer&#8217;s published specification for that hose type and dash size, and record the crimp diameter. If you are moving a machine from 100R2 to 100R16 to solve a routing problem, the fittings change with the hose, and it is worth confirming the ferrule part number before the first assembly is built.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-a-100r2-crimp-programme-does-to-a-compact-hose\">What a 100R2 Crimp Programme Does to a Compact Hose<\/h3>\n\n\n\n<p>The consequence of running a compact hose through a crimp programme written for a standard two-braid hose is not marginal, and it fails in two opposite directions depending on how the crimper was set.<\/p>\n\n\n\n<p>Table 8.

Every hose built to these specifications carries a printed layline \u2014 the text running along the cover \u2014 that states the specification, the size and the manufacturer&#8217;s code. Reading it takes a few seconds and prevents the most expensive mistake in hose replacement; the full method for decoding one is in our guide to <a href=\"https:\/\/www.henghuahose.com\/de\/how-to-read-a-hydraulic-hose-layline-size-pressure-sae-codes-replacement-guide\/\" target=\"_blank\" rel=\"noopener\">reading a hydraulic hose layline<\/a>.<\/p>\n\n\n\n<p>Table 9.

Measure the outside diameter with a caliper and compare it with the published OD for the size, then look at the cut end: one visible braid layer is a 100R1 or a compact single braid, two braid layers is a 100R2 or a 100R16, and a wire helix inside or outside the reinforcement means the hose is a suction and return construction rather than a pressure hose. Where the hose is still in service and the marking is unreadable, the safest route is to pull the assembly and let the distributor match it against a specification table rather than to match it on outside diameter 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\/sae-100r-hose-layline-marking-identification.jpg\" alt=\"Close-up of the printed layline on a hydraulic hose cover showing the SAE 100R specification code, dash size and manufacturer marking\" class=\"wp-image-5396\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r-hose-layline-marking-identification.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r-hose-layline-marking-identification-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r-hose-layline-marking-identification-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r-hose-layline-marking-identification-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r-hose-layline-marking-identification-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 2.

If a line regularly sees spikes above 2,000 psi, do not specify 100R1 on the strength of its steady-state rating. Where the pressure is between 2,000 and 3,000 psi, both 100R1 and 100R2 exist in the size range; the deciding factor is then impulse frequency, not the pressure number.<\/li>\n<li><strong>Confirm the dash size from flow, not from the old hose.<\/strong> A hose that has been replaced twice in the same size but keeps failing may be undersized for the flow rather than wrong for the pressure. As a working rule in mobile hydraulics, oil velocity above about 20 feet per second in a pressure line generates heat and pressure drop, and the fix is the next dash size up.<\/li>\n<li><strong>Measure the space and the bend.<\/strong> This is the step that decides the 100R2 vs 100R16 question. Measure the tightest radius the routing allows, add the fitting and crimp length at both ends, and compare against the published minimum bend radius. If the radius the routing allows is tighter than the bend radius published for the standard two-braid hose at that dash size (Table 4), the compact 100R16 is the answer (Table 6).<\/li>\n<li><strong>Check fluid and temperature at the hose, not at the reservoir.<\/strong> Measure the temperature where the hose runs, not at the reservoir: on a mobile machine the hose side of the circuit is normally well above the tank reading, and it is the hose figure that the compound has to survive. Water-based fluid lowers the ceiling further. Where the requirement exceeds the rubber range, the answer is a different material family rather than a different braid count.<\/li>\n<li><strong>Match the fittings and the crimp spec.<\/strong> Confirm the ferrule series for the chosen hose type, the crimp diameter, and that the assembly shop holds the specification.

The 100R1 vs 100R2 price step is roughly 20 to 30 percent per metre of the same size; a 100R1 is the least expensive of the three per metre, while a 100R2 costs that premium over it; and a 100R16 carries a further premium over the 100R2 \u2014 typically 15 to 40 percent depending on size and cover \u2014 because the compact construction requires tighter braiding tolerance and a thinner, more demanding cover extrusion.<\/p>\n\n\n\n<p>That premium is often repaid before the first year is out, because the compact hose changes the assembly rather than just the hose: a shorter routing, fewer clamps, less abrasion contact and a lighter assembly on a moving boom all reduce the failure rate that caused the replacement in the first place. The premium is not repaid when the compact hose is used in a wear zone with no protection, or when it is fitted with a ferrule that was specified for a 100R2. Both of those turn a routing improvement into a repeat failure.<\/p>\n\n\n\n<p>For buyers managing stock, the practical rule is to standardize on two specifications rather than three: 100R2 for general pressure lines and general service, plus 100R16 for the tight and moving circuits that generate most emergency callouts. Holding 100R1 as well is only economic where a fleet genuinely runs a large volume of low-pressure pressure lines, and even then the saving per metre is small relative to the inventory cost of a third specification, a third set of ferrules and a third crimp programme.<\/p>\n\n\n\n<p>If you are working out which two specifications to stock, send us those same four items \u2014 working pressure including spikes; bore or dash size; minimum bend radius the routing allows; fittings at both ends \u2014 together with the circuits you run most, and we will confirm which two constructions cover the fleet with the fewest SKUs and quote both.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-each-hose-fails-and-what-to-inspect\">How Each Hose Fails, and What to Inspect<\/h2>\n\n\n\n<p>Each specification fails in a characteristic way, and the failure pattern tells you whether the hose was the wrong choice or the right hose installed badly. In practice the SAE 100R1 vs 100R2 decision shows up more often in the failure log than in the specification sheet, because a single-braid hose under a shock-loaded circuit meets its pressure rating while running out of impulse life.<\/p>\n\n\n\n<p>Table 12. Characteristic failure modes by specification and what each one indicates<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th scope=\"col\">Failure seen<\/th><th scope=\"col\">Specification most often involved<\/th><th scope=\"col\">What it usually means<\/th><\/tr><\/thead><tbody><tr><td>Wire braid fatigue and a pinhole leak near a fitting<\/td><td>100R1<\/td><td>Line is seeing more impulse than a single braid can absorb<\/td><\/tr><tr><td>Cover cracked and braid exposed on the outside of a bend<\/td><td>100R2 or 100R16<\/td><td>Routing below the minimum bend radius, or abrasion without protection<\/td><\/tr><tr><td>Hose pulls out of the ferrule<\/td><td>100R16<\/td><td>Ferrule and crimp diameter specified for 100R2<\/td><\/tr><tr><td>Burst in a straight run, well below rated pressure<\/td><td>Any<\/td><td>Pressure spikes above the rating, or an incorrect crimp reducing the assembly&#8217;s capacity<\/td><\/tr><tr><td>Tube swollen and closing, flow falling<\/td><td>Any<\/td><td>Fluid incompatibility \u2014 check the tube compound against the fluid<\/td><\/tr><tr><td>Kink at the fitting rather than a clean bend<\/td><td>100R16 used where 100R1 was expected, or vice versa<\/td><td>Assembly length or orientation not matched to the minimum bend radius<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Inspection is the same on all three: look at the cover for cracks and exposed braid, feel along the length at the fitting for soft spots, check the crimp area for seepage, and confirm the layline is readable so the replacement can be matched. The ten failure causes we see most often, with the corrective action for each, are collected in our hydraulic hose failure troubleshooting guide. A hose that has been in continuous service for five years should be replaced on schedule even if it passes a visual check, because the failure mode that follows a long service life \u2014 internal tube hardening and braid fatigue \u2014 is not visible from the outside.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"faq\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"is-100r16-a-direct-replacement-for-100r2\">Is 100R16 a direct replacement for 100R2?<\/h3>\n\n\n\n<p>It is a functional replacement, not a dimensional one. A 100R16 carries the same or higher working pressure in the same dash size and bends to about half the radius, but its outside diameter, ferrule and crimp specification differ, which is why the 100R2 vs 100R16 decision is usually made on routing rather than on pressure. If the hose runs through a fixed guide, a clamp or a pulley sized for a 100R2, check the clearance before installing the compact hose.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"is-100r2-twice-as-strong-as-100r1\">Is 100R2 twice as strong as 100R1?<\/h3>\n\n\n\n<p>Not exactly, which is the detail most often missed in a 100R1 vs 100R2 summary. In the same bore, a 100R2 is rated about 1.80 times the working pressure of a 100R1 at 1\/4 inch (5,000 psi against 2,780 psi), 1.75 times at 3\/8 inch, 1.72 times at 1\/2 inch, and up to 2.42 times at 1-1\/4 inch. The bigger practical difference is impulse life: the second braid layer absorbs repeated pressure spikes far better, which is why shock-loaded circuits specify 100R2 even where the steady pressure would allow a 100R1.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-the-100r2-vs-100r16-pressure-rating-at-3-4-inch\">What is the 100R2 vs 100R16 pressure rating at 3\/4 inch?<\/h3>\n\n\n\n<p>On the tables used here, the -12 published working pressures are 17.2 MPa (2,500 psi) for SAE 100R2AT and 21.5 MPa (3,120 psi) for 100R16 (EN 857 2SC), so the compact hose is rated about 25 percent higher at that size. The gap widens as the bore grows, because the compact construction is published to the EN 857 2SC table while 100R2 is published to its own. Read the figure from a hydraulic hose working pressure chart at the exact dash size you are ordering: both specifications fall with bore, and they do not fall at the same rate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-the-difference-between-100r2-and-100r2at\">What is the difference between 100R2 and 100R2AT?<\/h3>\n\n\n\n<p>The AT suffix describes the cover and the assembly method, not the pressure class. 100R2AT is a no-skive hose with a thinner cover, so the ferrule is crimped directly over the cover; the standard 100R2 has a thicker cover and more abrasion margin. Both hold the same pressure class, and the AT version is lighter with a smaller outside diameter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"is-100r1-cheaper-than-100r2-and-100r16\">Is 100R1 cheaper than 100R2 and 100R16?<\/h3>\n\n\n\n<p>Yes, per metre: the 100R1 to 100R2 step is roughly 20 to 30 percent and the 100R2 to 100R16 step a further 15 to 40 percent, depending on size and cover \u2014 a market range rather than a published figure. Where that saving is usually not worth taking is stock rather than hose. A third specification needs its own ferrules, its own crimp programme and its own shelf space, so on a machine that runs only a few low-pressure pressure lines the inventory cost of adding 100R1 exceeds the per-metre saving, and the answer is to keep 100R1 out of the stores list altogether.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"is-100r16-the-same-as-2sc\">Is 100R16 the same as 2SC?<\/h3>\n\n\n\n<p>They are the same construction class published by two standards bodies. 100R16 corresponds to EN 857 Type 2SC and ISO 11237 Type R16, and a single hose often carries both markings on the cover. In other words, the 2SN vs 2SC question on a European machine is the same decision as 100R2 vs 100R16 on a North American one. Pressure tables are close but not always identical between editions, so confirm the actual figure on the datasheet for the size you are ordering.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"which-hose-should-i-stock-as-a-distributor\">Which hose should I stock as a distributor?<\/h3>\n\n\n\n<p>Two specifications rather than three: 100R2 in every dash size the fleet uses, plus 100R16 in the -4 to -12 range that the tight and moving circuits call for. 100R1 earns shelf space only where a customer base genuinely consumes a large volume of low-pressure pressure lines, because the per-metre saving is small against the cost of a third ferrule series and a third crimp programme. Add 100R4 for suction lines and 100R3 or 100R6 for return lines where those circuits are serviced, and keep the layline string of every stocked hose in the parts record so replacements are matched by specification rather than by sight.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-pressure-is-a-1-2-inch-100r16-rated-for\">What pressure is a 1\/2 inch 100R16 rated for?<\/h3>\n\n\n\n<p>On the EN 857 2SC table used here, a -8 (1\/2 inch) 100R16 is published at 27.5 MPa (3,990 psi) working pressure, with minimum burst pressure specified at four times that figure. Ratings fall as bore increases, so confirm the value for the exact size rather than assuming the 1\/2 inch figure applies to the whole range, and read the psi or bar column from the same published table rather than from a second source.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-a-100r2-hose-be-crimped-with-a-100r16-ferrule\">Can a 100R2 hose be crimped with a 100R16 ferrule?<\/h3>\n\n\n\n<p>No \u2014 it depends on the ferrule, not on the dash size. A ferrule published for a 100R2 hose is matched to a standard two-braid build, while a 100R16 needs the ferrule and crimp diameter published for the compact build, even when the two hoses carry the same dash size. The two look close enough on the bench that an under-compressed or over-compressed crimp passes a visual check, which is why the crimp diameter belongs on the batch card and the ferrule part number should be confirmed by series rather than assumed to carry across.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-does-100r16-6-mean-on-a-layline\">What does 100R16-6 mean on a layline?<\/h3>\n\n\n\n<p>It is a compact two-braid hose in 3\/8 inch nominal bore. 100R16 is the SAE J517 specification number, and -6 is the dash size, read in sixteenths of an inch \u2014 6\/16 inch is 3\/8 inch. A fully marked hose also carries the manufacturer&#8217;s code and the working pressure, and often the equivalent European code EN 857 2SC or ISO 11237 R16, so the same hose can be identified from either side of the standard. The -6 on its own tells you the bore; the specification code in front of it is what tells you the construction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-the-100r16-temperature-range-in-cold-weather\">What is the 100R16 temperature range in cold weather?<\/h3>\n\n\n\n<p>The rubber grades behind 100R16 are rated -40 \u00b0C to +100 \u00b0C continuously, with short excursions to about +120 \u00b0C \u2014 the same envelope as SAE 100R1 and SAE 100R2, and the thinner compact cover does not change the low-temperature limit. What does change the limit is the fluid: on water-glycol fluid the continuous ceiling falls to around +70 \u00b0C in most published tables, whatever the hose type. Cold-weather failures on all three hoses are more often caused by routing that forces a bend while the hose is still stiff than by the compound itself, so leave the straight lead-in behind the fitting intact in winter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"do-100r1-100r2-and-100r16-have-the-same-impulse-life\">Do 100R1, 100R2 and 100R16 have the same impulse life?<\/h3>\n\n\n\n<p>They are tested to the same impulse procedure \u2014 EN ISO 6803, at 133 percent of working pressure, at +100 \u00b0C, for a minimum of 200,000 cycles \u2014 but they do not survive it equally. The second braid layer shares the load across twice the wire, so a two-braid hose lasts longer under the same pulse profile, and the compact 100R16 has less cover material to shed heat from. On a circuit that pulses hard and often, ask the supplier for the impulse report at your dash size rather than comparing working-pressure numbers, because the pulse profile and not the steady rating is what decides the replacement interval.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"final-verdict-match-the-rating-then-verify-the-supplier\">Final Verdict: Match the Rating, Then Verify the Supplier<\/h2>\n\n\n\n<p>The choice in a 100R1 vs 100R2 vs 100R16 decision is settled by three numbers in this order: the maximum pressure the circuit actually sees, the minimum bend radius the routing allows, and the temperature and fluid at the hose. If the pressure is under about 2,000 psi and there is room to route, 100R1 is the economical answer. If the pressure is between 2,000 and 5,000 psi, 100R2 is the general-purpose answer and remains the hose most machines are built around. If the bend radius is the constraint \u2014 which is the case on most modern mobile equipment \u2014 the compact hydraulic hose delivers the same pressure class in roughly half the space, provided the fittings and crimp specification change with it.<\/p>\n\n\n\n<p>Where the pressure rises above about 5,000 psi at 3\/4 inch and larger, none of these three is correct and the line needs a spiral hose.<\/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\/sae-100r16-compact-hose-cylinder-installation.jpg\" alt=\"SAE 100R16 compact hydraulic hose installed on a moving cylinder with a tight bend radius and crimped fittings at both ends\" class=\"wp-image-5397\" srcset=\"https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r16-compact-hose-cylinder-installation.jpg 800w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r16-compact-hose-cylinder-installation-300x225.jpg 300w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r16-compact-hose-cylinder-installation-768x576.jpg 768w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r16-compact-hose-cylinder-installation-16x12.jpg 16w, https:\/\/www.henghuahose.com\/wp-content\/uploads\/2026\/09\/sae-100r16-compact-hose-cylinder-installation-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Figure 3. The compact build of 100R16 is what allows a pressure line to bend tightly behind the fitting without kinking \u2014 the routing that most often forces a specification change.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"manufacturing-notes-how-these-three-hoses-are-made-at-henghua\">Manufacturing Notes: How These Three Hoses Are Made at HENGHUA<\/h2>\n\n\n\n<p>HENGHUA manufactures the three specifications compared in this guide \u2014 SAE 100R1AT, SAE 100R2AT and SAE 100R16 compact hose, together with the constant-pressure SAE 100R17 companion \u2014 in inside diameters from 6 mm to 51 mm, alongside the spiral (100R12, 100R13, 100R15) and textile-braid (100R3, 100R6) families that the decision tables above point to when a line leaves the medium-pressure range. Production runs in an 18,000 m\u00b2 facility with in-house rubber mixing, so tube compound, wire braid and cover are controlled in one plant rather than assembled from bought-in components, and the braiding lines hold tension to \u00b10.05 mm.<\/p>\n\n\n\n<p>Three details of that process are relevant to the comparison in this article. Pressure and dimensional data are published per dash size rather than quoted as a family range, so the working pressure, proof pressure, minimum bend radius and weight of the exact size you order can be checked before anything is crimped. Braided hoses are impulse-tested beyond 400,000 cycles, and finished assemblies are 100% proof-tested with the crimp record retained for the batch. And because the same plant mixes, braids, extrudes, crimps and tests, matching the ferrule to the hose type \u2014 the failure mode covered under &#8220;Fittings, Ferrules and Crimp Specs Are Not Interchangeable&#8221; \u2014 is a production control rather than something left to the customer to discover in the field.<\/p>\n\n\n\n<p>Certification and approvals held across the range include ISO 9001, ISO 18752, MSHA, CE, CCS, ABS and DNV, with RoHS and California Proposition 65 compliance on the relevant lines. HENGHUA supplies distributors, OEM programmes and maintenance operations in more than 70 countries, with 48-hour custom sampling, seven-day turnaround on standard bulk orders, fittings in metric, BSP, JIC, NPT and ORFS styles, and test reports supplied with the shipment.<\/p>\n\n\n\n<p>If you are working through a specification decision and want it confirmed against real data, send us four items
