The SS04 hydraulic hose is a four spiral wire reinforced soft rubber hose designed for high pressure and high temperature hydraulic applications. The tube is made of oil-resistant synthetic rubber, reinforced with four spirals of high-tensile steel wire, and covered with oil, abrasion, ozone and weather resistant synthetic rubber. It offers higher pressure resistance and temperature resistance than EN 853 standard hoses, with a more flexible hose body. It can be used as a replacement for EN 853 standard hoses and is widely used for mining machinery and other heavy-duty equipment.Zhongxu, a professional hydraulic hose manufacturer, produces SS04 hoses with high-tensile steel wire spiral reinforcement for demanding hydraulic systems.
Zhongxu produces SS04 hoses strictly to EN 856 4SP/4SH standards, with 100% proof pressure testing on every batch.
