As a professional rubber hose solution, it follows a strict standard to ensure safety and performance. Definition of this product is a high-pressure delivery line that combines flexibility with resistance to abrasion and material clogging. When you need to supply reliable equipment for spraying applications, this hose meets global requirements. Available from china, it offers a balance of cost and quality for contractors worldwide.<\/p>\n<p>The construction features a NR\/SBR synthetic rubber tube and cover, reinforced with four or six plies of synthetic textile including a static wire. This Wire Braided Hose-style reinforcement provides the structure needed for High Pressure Hose applications up to 600psi. Unlike a Wire Spiral Hose, the textile plies keep the hose lightweight and flexible while maintaining burst resistance. The cover is black with a cloth impression for improved handling and wear resistance.<\/p>\n<p>Key performance parameters include a working pressure of 40 bar (600 psi) and a bursting pressure of 120 bar (1800 psi), offering a standard 3:1 safety factor. The temperature range spans -40&deg;C to +70&deg;C, suitable for extreme conditions. Lengths are 61 meters (183 feet) per roll, reducing coupling needs. Four key advantages are: high abrasion resistance for sand and grout, flexibility for easy handling on site, static wire for safety, and a smooth bore to prevent material buildup.<\/p>\n<p>Primary applications include spraying plaster, grout injection, and sand blasting in construction. Equipment includes plaster pumps, grout pumps, and shotcrete machines. The hose solves three core pain points: frequent hose blowouts from pressure spikes, rapid cover wear from abrasive materials, and stiffness that makes coiling difficult. Quality is assured by manufacturing processes in a certified factory, with support for technical queries and service for replacement.<\/p>\n<h2>Product Advantages<\/h2>\n<ul>\n<li>\n<p><strong>Abrasion-Resistant Cover<\/strong>: The NR\/SBR cover withstands continuous contact with sand, cement, and plaster, extending service life.<\/p>\n<\/li>\n<li>\n<p><strong>High Flexibility at Low Temperatures<\/strong>: Remains workable down to -40&deg;C, simplifying winter construction.<\/p>\n<\/li>\n<li>\n<p><strong>Static Wire for Safety<\/strong>: Dissipates static electricity when spraying dry materials, reducing spark risks.<\/p>\n<\/li>\n<li>\n<p><strong>Cost-Effective Bulk Supply<\/strong>: Available at competitive price and cost per meter for wholesale and bulk orders.<\/p>\n<\/li>\n<li>\n<p><strong>OEM ODM Ready<\/strong>: <strong>Factory<\/strong> can customize length, printing, and packaging for brand owners.<\/p>\n<\/li>\n<li>\n<p><strong>Complete Assembly Support<\/strong>: Compatible with hose assembly, crimped fittings, reusable fittings, adapters, flanges, protective sleeves, and guards.<\/p>\n<\/li>\n<\/ul>\n<p><strong>Applicable Users<\/strong>: Construction contractors, plastering companies, grouting specialists, facility maintenance teams, and equipment rental companies.<\/p>\n<h2>Detailed Technical Specifications Table<\/h2>\n<div class=\"ds-scroll-area\">\n<table>\n<thead>\n<tr>\n<th>Code<\/th>\n<th>Inch<\/th>\n<th>Inside Diameter (mm)<\/th>\n<th>Outside Diameter (mm)<\/th>\n<th>Working Pressure (bar\/psi)<\/th>\n<th>Bursting Pressure (bar\/psi)<\/th>\n<th>Length (m\/ft)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>PAGH025<\/td>\n<td>1&#8243;<\/td>\n<td>25<\/td>\n<td>38<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH032<\/td>\n<td>1-1\/4&#8243;<\/td>\n<td>32<\/td>\n<td>50<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH038<\/td>\n<td>1-1\/2&#8243;<\/td>\n<td>38<\/td>\n<td>56<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH051<\/td>\n<td>2&#8243;<\/td>\n<td>51<\/td>\n<td>73<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH064<\/td>\n<td>2-1\/2&#8243;<\/td>\n<td>64<\/td>\n<td>84<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH076<\/td>\n<td>3&#8243;<\/td>\n<td>76<\/td>\n<td>102<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH089<\/td>\n<td>3-1\/2&#8243;<\/td>\n<td>89<\/td>\n<td>113<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<tr>\n<td>PAGH102<\/td>\n<td>4&#8243;<\/td>\n<td>102<\/td>\n<td>127<\/td>\n<td>40 \/ 600<\/td>\n<td>120 \/ 1800<\/td>\n<td>61 \/ 183<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><em>Note: For complete pdf specification sheets or drawings, contact our supplier team.<\/em><\/p>\n<h2>Structure and Materials<\/h2>\n<ul>\n<li>\n<p><strong>Tube (Inner Layer)<\/strong>: NR\/SBR synthetic rubber, smooth bore to minimize flow resistance and prevent material clogging.<\/p>\n<\/li>\n<li>\n<p><strong>Reinforcement Layer<\/strong>: Four or six plies of high-strength synthetic textile with an embedded static wire.

The four to six textile plies are engineered to withstand repeated pressure surges from positive displacement pumps (common in plaster sprayers) without becoming rigid. The static wire serves a critical safety function: when dry sand or cement powder flows at high velocity, static charge can build up. The wire provides a path to ground, preventing electrostatic discharge that could ignite dust or shock operators. This hybrid construction (textile for flexibility + static wire for safety) is the solution for construction material transfer.<\/p>\n<h2>Application Industries<\/h2>\n<h3>4.5.1 Key Application Scenarios<\/h3>\n<ul>\n<li>\n<p><strong>Building Construction<\/strong>: Spraying plaster on interior\/exterior walls.<\/p>\n<\/li>\n<li>\n<p><strong>Civil Engineering<\/strong>: Grouting for soil stabilization and foundation repair.<\/p>\n<\/li>\n<li>\n<p><strong>Minera\u00e7\u00e3o<\/strong>: Backfilling with cemented paste or sand.<\/p>\n<\/li>\n<li>\n<p><strong>Tunneling<\/strong>: Applying shotcrete or grout behind liners.<\/p>\n<\/li>\n<li>\n<p><strong>Facility Maintenance<\/strong>: Repairing spalled concrete or applying coatings.<\/p>\n<\/li>\n<\/ul>\n<h3>4.5.2 Precise Selection Professional Guide<\/h3>\n<p><strong>1. Hose Assembly Solutions<\/strong><br \/>For optimal performance, use crimped fittings with a smooth bore to match the hose ID. We recommend adapters or flanges for larger diameters (3&#8243; and 4&#8243;). Protective sleeves and guards are advised where hoses run over sharp edges. Pre-assembled hose assembly from our factory ensures correct crimping and reduces on-site errors.<\/p>\n<p><strong>2.

Use a specialized High Pressure Hose with NBR tube for oil.<\/p>\n<p><strong>Q2: What is the minimum bend radius?<\/strong><br \/>A: Approximately 10x the outside diameter. For 38mm OD, minimum bend is 380mm. Tighter bending may reduce burst pressure.<\/p>\n<p><strong>Q3: Do you offer <strong>OEM ODM<\/strong> services?<\/strong><br \/>A: Yes. As a manufacturer, we can print your brand on the cover, customize carton labels, and provide specific lengths.<\/p>\n<p><strong>Q4: Can I <strong>buy<\/strong> a <strong>sample<\/strong> before <strong>bulk<\/strong> order?<\/strong><br \/>A: Yes. Sample lengths (up to 5m) are available at nominal cost. Shipping is arranged via courier.<\/p>\n<p><strong>Q5: What <strong>fittings<\/strong> are compatible?<\/strong><br \/>A: Standard camlock, threaded adapters, and flanges for 2&#8243; to 4&#8243; sizes. We supply crimped fittings as hose assembly.<\/p>\n<p><strong>Q6: Is there a <strong>discount<\/strong> for <strong>wholesale<\/strong> or <strong>bulk<\/strong> orders?<\/strong><br \/>A: Yes. Price per meter decreases significantly above 500m. Contact our distributor or wholesaler team for a quote.<\/p>\n<p><strong>Q7: Where can I download the <strong>pdf specification<\/strong>?<\/strong><br \/>A: Request the datasheet from our supplier portal or email support.<\/p>\n<p><strong>Q8: How does the static wire work?<\/strong><br \/>A: The wire runs along the hose length. You must connect a grounding clamp from the wire to true earth at the pump end.<\/p>\n<p>Ready to improve your plastering and grouting operations?
