SAE J189 Standard Low Pressure Flexible Power Steering Return Pipe Hose
Power steering hoses are always in pairs - high pressure and low pressure. One transfers power steering liquid from the pump to the mechanism, while the other transfers liquid back to the pump. Both hoses work together to make the steering system operate.
Low pressure power steering hose is especially designed for low operating pressure up to 175 psi. The inside tube is NBR, and the outside cover is CSM, which has excellent resistance to ozone, sunlight, heat, and aging. Polyester spiral reinforcement allows the hose to withstand temperatures up to 300°F.
