High Pressure Thermoplastic Hydraulic Hose SAE 100 R7 R8 China Factory Suppliers
Our High Pressure Thermoplastic Hydraulic Hoses, compliant with SAE 100 R7/R8 and EN855 R7/R8 standards, are engineered for precision performance in demanding fluid power systems. Unlike conventional rubber hoses, these advanced thermoplastic solutions feature a high-quality oil-resistant inner tube and high-tensile synthetic fiber reinforcement, offering an optimal balance of lightweight construction and superior pressure resistance for industrial and mobile applications.
Designed to eliminate internal carbon dust and reduce system contamination, these hoses ensure the longevity of critical valves, pumps, and actuators. Whether you require the medium-pressure versatility of the R7 series or the heavy-duty endurance of the R8 series, our direct-factory manufacturing ensures consistent burst pressure ratings, impulse durability, and thermal stability across every batch, significantly reducing downtime and maintenance costs for OEM and aftermarket users.

Frequently Asked Questions
The primary difference is the pressure rating and reinforcement. R7 is designed for medium-pressure applications and prioritized agility, while R8 features double-layer high-strength reinforcement for higher pressure loads and superior burst strength.
Yes, they are designed for petroleum-based hydraulic fluids, mineral oil, gasoline, fuel oil, lubricating oil, emulsion, and glycol solutions, offering excellent chemical resistance.
Thermoplastic hoses are lighter, more flexible, and do not produce internal abrasion dust, which keeps the hydraulic system cleaner and extends the life of pumps and valves.
Absolutely. The outer cover is specifically formulated for abrasion resistance and environmental stability, making them dependable for road construction and outdoor industrial sites.
Our R7/R8 hoses are engineered for a specific bend radius stability. We recommend selecting the appropriate hose grade based on the tightness of your routing to ensure no structural collapse occurs.
Yes, as a direct manufacturer, we support full customization of hose length, reinforcement levels, and connection specifications to fit your specific machinery requirements.
