A power steering seal is a small but critical component in the power steering system of a vehicle. It is located between the power steering pump and the steering gear or rack, and its purpose is to prevent fluid from leaking out of the system.

The power steering system uses hydraulic pressure generated by the pump to assist the driver in turning the wheels. The power steering fluid travels through hoses and pipes to the steering gear, where it applies pressure to the gears to make the wheels turn. The power steering seal is responsible for preventing fluid from leaking out of the system, which would cause the fluid level to drop and the power steering system to become less effective or fail altogether.

In summary, the power steering seal is important because it helps to ensure that the power steering system operates effectively and efficiently by preventing fluid from leaking out of the system. If the seal fails, it can lead to a loss of power steering fluid, which can cause the system to fail and make it difficult for the driver to steer the vehicle.
