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 and extreme temperature fluctuations.
Constructed with multiple layers, these hoses feature a synthetic rubber or thermoplastic inner tube resistant to hydraulic fluid degradation, reinforcement layers (braided steel wire or textile mesh) for pressure containment, and a weather-resistant outer cover to protect against abrasion and ozone damage.
