Rubber Heater Hose SAE J20 R3 Introduction
Heater hose can convey hot water and antifreeze for Vehicle Heating and Cooling Systems. The inner layer is special rubber, the outer layer is heat-resistant and weather-resistant EPDM material, and the reinforcement layer is high-strength fabric enhanced durability. The three-layer structure makes the heater hose have excellent weather resistance, wear resistance and oil resistance. Sizes range from 3/8″ to 1″, working pressure is 10bar or 20bar, burst pressure reaches 83bar, and the safety factor can reach four times.
