EN 856 4SP steel wire spiraled hydraulic hose is suitable for mine hydraulic support and the related equipment. The hose is resistant to flame and static. It is almost similar to EN 856 4SH steel wire spiraled hydraulic hose in structure, but it can bear higher working pressure than EN 856 4SH steel wire spiraled hydraulic hoses under the same temperature. It is composed of three parts: tube, reinforcement and cover. The tube is made from black oil resistant synthetic rubber, making the hose resistant to abrasion and corrosion. The reinforcement is made from four layers of high tensile and high strength spiraled steel wire which is specially designed for rubber hose, making the hose perfectly resistant to high pressure. The cover is made from high quality black synthetic rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, oil and aging. More importantly, the appearance is cloth surface rubber. Therefore, the hose has longer service life.
