High-pressure Hose
High-pressure hose
High-pressure series hoses include steel-wire-reinforced polyurethane hoses and steel-wire-reinforced nylon hoses. Both hoses adopt high-tensile steel wire braiding for their reinforcement layers, delivering excellent pressure resistance.The difference between the two is the inner tube material; nylon offers superior pressure resistance.
Products Description
Hoses of the high-pressure series feature a smooth outer surface, small bending radius, excellent wear resistance, great flexibility and easy installation. They resist corrosion from many chemicals, with smooth inner walls for low resistance and smooth fluid flow. The minimum burst pressure of each type of hose is three times its working pressure.
