A power steering pressure hose is a component within a vehicle's steering wheel system. It helps to transport hydraulic power steering fluid to the power steering rack and power steering pump from the reservoir. This fluid only works in a pressurized system.

Any vehicle comprises two power steering pressure hoses:

1. The High-pressure hose: Transports fluid from the pump to the rack.
2. The Low-pressure hose: Transports fluid back from the rack to the pump.

Pressure hoses and return hoses are rubber products and have a limited life span. If the vehicle is more than 10 years old and the power steering components are being replaced, then all rubber hoses should be replaced during that service period to ensure safety and performance.
