A power steering hose is a critical component in vehicle hydraulic steering systems, designed to transport pressurized hydraulic fluid between the power steering pump, steering gear/rack, and reservoir. These flexible yet durable hoses withstand continuous exposure to high pressures (typically 150-1,500 PSI) and extreme temperature fluctuations (-40°F to +300°F).
Primary Types:
1. High-Pressure Supply Hoses: Connect the pump to the steering gear, handling peak system pressures.
2. Low-Pressure Return Hoses: Direct excess fluid back to the reservoir under minimal pressure.
