Engineered to meet exact SAE J517 and SAE 100 R5 specifications, this fluid transmission line guarantees compliance with strict international regulatory requirements. By adhering to mainstream quality management systems, it ensures smooth market access and equipment compliance for global procurement programs. The construction features a single high-tensile steel wire braid reinforcement enveloped in a rugged textile cover, delivering a consistent working pressure range of 10.3–20.7 MPa (1500–3000 psi). This makes it an exceptionally dependable choice for medium-pressure hydraulic systems requiring continuous, stable flow.
At the core of this steel wire braided line is a premium NBR (Nitrile Butadiene Rubber) inner tube. This material provides a smooth internal bore that minimizes fluid turbulence while offering exceptional resistance to petroleum-based hydraulic oils, synthetic lubricants, compressed air, and water-glycol fluids. It maintains its structural integrity and remains supple across extreme temperature variations, operating reliably from -40°C to +100°C. Users will notice it retains its bending flexibility in freezing environments while resisting thermal aging and brittleness during prolonged exposure to high engine heat.
Unlike standard rubber exteriors, the outer textile braided cover of our SAE 100 R5 line presents a distinctive, tightly woven tactile finish. This rugged exterior provides exceptional defense against physical abrasion, ozone exposure, and UV degradation, making it highly suitable for outdoor mobile operations. Its lightweight profile and small minimum bending radius allow technicians to route the line effortlessly through the narrow, complex chassis spaces of commercial vehicles and compact machinery without forcing unnatural kinks.
Safety and longevity are paramount in fluid power applications. This medium-pressure line is engineered with a strict 4:1 safety factor, meaning its tested burst pressure exceeds four times the rated working pressure. Before leaving the facility, the product undergoes rigorous pulse fatigue testing and ozone aging evaluations. This ensures it can withstand the frequent, aggressive pressure spikes and continuous mechanical vibrations inherent in automotive brake lines and heavy-duty power steering circuits without weeping or structural failure.
We provide deeply customized fluid transmission solutions to match specific engineering blueprints. This includes bespoke inner diameters, precise cut lengths, and specialized fluid-resistant compound formulas. Furthermore, the line is fully compatible with international standard fittings such as JIC, NPT, and BSP. We offer precision-crimped, ready-to-install assemblies that significantly reduce on-site labor time and assembly costs. With robust mass production capabilities and tailored brand marking options on the hose body, we deliver highly cost-effective, factory-direct solutions tailored for volume procurement.
The specifications detailed below represent the exact engineering tolerances and material capabilities of our SAE 100 R5 product line. Each parameter is continuously verified through stringent batch testing protocols, ensuring that the physical dimensions, thermal endurance, and pressure ratings translate directly to reliable, leak-free performance in your demanding fluid power applications.

Our SAE 100 R5 line is specifically tailored for the rigorous demands of commercial vehicle brake lines and power steering circuits. The single high-tensile steel wire braid combined with the abrasion-resistant textile cover withstands continuous medium-pressure cycles and frequent pulse loads. It ensures reliable, instantaneous fluid response even under severe chassis vibration and exposure to harsh road debris.
Widely utilized in heavy-duty tractors, harvesters, and specialized farm equipment, this textile-covered line excels in agricultural settings. Its superior resistance to weather, ozone, and physical abrasion allows it to endure long-term outdoor field operations involving mud, dust, and direct sunlight. The stable medium-pressure performance guarantees consistent fluid transmission for implement lifting and steering mechanisms.
Perfectly suited for compact construction machinery such as skid steer loaders, vibratory rollers, and aerial work platforms. The inherently flexible structure and tight bending radius allow technicians to route the lines easily through congested engine compartments and articulated joints. It delivers outstanding pulse resistance, maintaining secure fluid power for heavy-duty mobile attachments.
For stationary applications like industrial machine tools, injection molding presses, and centralized hydraulic power units, this steel wire braided line provides unwavering medium-pressure fluid delivery. The premium NBR inner tube prevents oil degradation and weeping, supporting continuous, reliable operation across automated production floors where downtime is costly.
Beyond hydraulics, this versatile SAE 100 R5 product is highly effective for compressed air lines and automated lubrication circuits in transit buses, heavy trucks, and municipal utility vehicles. It handles medium air pressure effortlessly while surviving harsh outdoor environments, ensuring safe, stable transmission of air and viscous lubricants to critical moving components.
Pre-Installation Inspection: Before assembly, perform a visual and tactile check of the SAE 100 R5 line. Run your hands over the textile cover to ensure there are no snags or structural damages from transit. Verify that the inner diameter, length, and pressure rating perfectly match your system's exact requirements.
Proper Routing & Assembly: Install the line in a relaxed state without twisting or applying torsional stress. Adhere strictly to the minimum bending radius to prevent restricting the internal flow. Route the assembly away from sharp metal edges, moving belts, and extreme high-temperature exhaust sources. Utilize appropriate mounting clamps to minimize vibration fatigue.
Fitting Connection: Ensure all JIC, NPT, or BSP fittings are tightened to the manufacturer's specified torque. Over-tightening can damage the threads, while under-tightening will lead to weeping and pressure loss.
Ongoing Maintenance & Monitoring: During routine equipment servicing, visually inspect the woven outer cover for signs of excessive friction wear, deep cracks, or fluid saturation. Listen for any audible hissing that might indicate compressed air leaks, and feel the line for unnatural hardening or localized bulging, which signals internal aging. Prompt replacement upon detecting these signs ensures the continued safe operation of your fluid power system.
