Application：It is suitable for transporting water-based, petroleum-based hydraulic oil and biodegradable hydraulic oil in harsh working environments such as excavators, construction machinery, mining machinery and agricultural machinery, etc.
Inner Layer：Oil resistant synthetic rubber
Reinforcement：4-layered high-strength super-flexible steel wire
Outer Layer：Wear-resistant, weather-resistant synthetic rubber (weather-resistant for 5 years, warranty for 3 years)
Characteristic：Low bending-bending radius is 50% lower than DIN EN853 standard; high-pressure-pressure is 30%~40% higher than DIN EN853 standard; long life.
Hose Fitting：It adopts high-quality carbon structural steel, the core material is 45# steel, the nut material is 35# steel, and the sleeve is 20# steel, which conforms to the national, British and American national standards. The joint sealing is made of hydrogenated nitrile rubber (10 years of aging resistance) Above) Use the one-piece hose connector specially provided by Litong, with pulse >= 1 million times.
Temperature Range：-40℃~+85℃(-40℉~+185℉)H
