Hydraulic hose is superior to the ordinary hose in both performance and function. The inner rubber is to enable the medium withstand a certain pressure, meanwhile to prevent the steel wire from being eroded. External rubber has the characters of aging resistance, fireproofing, wear resistance etc. The reinforcement of steel wire to be divided into one to six layers according to different pressure requirements. It uses for hydraulic power to transport water, gas, high pressure oil mediums, the liquid can be continuously circulated to keep the energy can be transmitted.
