Product Description

SAE J189 Standard Car Vehicle Truck Low Pressure High Tensile Performance NBR CSM Rubber Hose

Power Steering Hose

Power steering hoses operate in pairs: high pressure and low pressure. One transfers power steering liquid from the pump to the mechanism, while the other returns liquid back to the pump. This dual-hose system ensures smooth steering operation.

Key Design: Specifically engineered for low operating pressure up to 175 psi. Features an NBR inner tube and CSM outer cover for superior resistance to ozone, sunlight, heat, and aging.
