Construction: • Inner tube: smooth seamless polyester tube • Cover: black non-perforated polyurethane, resistant to oil, ozone and weathering • Reinforcement: single braid of high tensile steel wire Application: Hose range suitable for applications such as general hydraulics, high-pressure hydraulic systems, machine tools, mobile equipment, agricultural equipment, marine steering. Burst pressure exceeds four times the working pressure. NB: the working and test pressures for this hose family are higher than the 100R1/R7 standard. Therefore this hose exceeds the performance set forth in the SAE J517 100 R7 series hydraulic hose.
