25mm Pressure Hose Noise Reduction Design High Pressure Fatigue Resistant
Description
Designed for extreme-pressure applications, our armored hydraulic hose features multi-layer steel wire reinforcement, ensuring burst pressures up to 10,000 PSI. The oil-resistant synthetic rubber inner tube and abrasion-proof thermoplastic cover provide superior durability in construction, mining, and heavy machinery. With a flexible 5D bend radius and temperature range of -40°C to +120°C, it excels in dynamic hydraulic systems. Certified to SAE J517 and ISO 18752, it’s ideal for excavators, presses, and industrial hydraulics where reliability is non-negotiable.
