This high-temperature resistant hydraulic hose assembly is built with an innovative dual-layer composite of nitrile rubber and silicone rubber. The inner nitrile layer provides excellent oil resistance, sealing, and resistance to media swelling, while the outer silicone layer delivers outstanding high-temperature stability and low-temperature flexibility. Together they cover an ultra-wide temperature range from -40°C to +300°C, with no softening at high temperatures and no brittleness or cracking at low temperatures. The hose is compatible with water-glycol, various hydraulic oils, clean water, emulsions, and other industrial fluids — one product suits multiple media, reducing procurement and inventory complexity.

The working pressure spans a full high-pressure gradient from 5 MPa to 42 MPa, supported by a high-strength multi-layer braided reinforcement structure. It resists high-pressure bursts, pulse impacts, and instantaneous pressure spikes, ensuring stable, leak-free performance under heavy-duty cyclic loading and equipment start-stop fluctuations. The assembly is integrally formed by CNC precision crimping with high-strength alloy steel couplings, providing tight, leak-proof joints that are easy to install and remove.

Custom-engineered for extreme conditions in oil refining, shipbuilding, chemical processing, iron and steel, casting, and other heavy industries, it withstands high-temperature baking, acid-alkali corrosion, media erosion, and continuous heavy-duty operation. Every assembly passes rigorous factory testing — including burst, thermal cycle aging, multi-media immersion, pulse fatigue, and tightness checks — to deliver long service life, reduced maintenance downtime, and reliable safety for high-temperature, high-pressure fluid transport and hydraulic systems.
