Hydraulic rubber hose is a key connecting element used to transport working medium (such as hydraulic oil, water-based liquid, etc.) in hydraulic system. It is specially designed for power transmission under high pressure, pulse and harsh operating conditions. The typical structure consists of an inner rubber layer (medium corrosion resistance), a reinforced layer (woven or wound by high strength steel wires to withstand pressure) and an outer rubber layer (wear resistance, weather resistance, oil corrosion resistance). This multi-layer design ensures excellent flexibility, pressure resistance and durability of the hose to withstand system pressures, temperature variations and external mechanical stresses, making it an indispensable flexible piping solution for construction machinery, industrial equipment and mobile hydraulic applications.
