Hydraulic rubber hose is a type of rubber hose which superior to ordinary rubber hose whatever in performance or in function. It is mainly spiral by inner rubber layer and middle rubber layer and several coils of steel wire. The inner rubber’s function is to allow the conveyed medium to withstand a certain pressure and meanwhile to prevent the steel wire be corroded. The outer rubber layer is to prevent the steel wire from receiving other types of damage. That makes steel wire as framework material plays a certain role in reinforcement. Hydraulic rubber hose not only can use hydraulic power to transport media such as water and air, but also transmit high-pressure media such as oil, so that it can ensure the continuous circulation of liquid and energy transfer.
