O-rings for power steering hose

The power steering system relies on a range of components to function efficiently, with the O-ring playing a crucial role in maintaining the integrity of the connections. The hardline typically measures 3/8 inch, while the O-ring section tapers down to 5/16 inch, conforming to the SAE AS568-011 specification.

After encountering an issue with a leaking power steering gear box and a noisy power steering pump, I was on a mission to source the correct O-ring. Unfortunately, my local auto parts store only recommended an AC O-ring, which, although it fit, was constructed from Viton rather than the original Buna N material used in factory installations. Thankfully, Grainger came through with the right solution. The O-ring specifications remain consistent, with hardlines typically at 3/8 inch and O-ring areas at 5/16 inch.

The O-ring for a power steering hose may be a small component, but its importance cannot be overstated. Typically manufactured from rubber or similar elastomeric materials, this O-ring ensures a secure seal between the power steering hose and various elements of the power steering system, such as the pump or the steering gear box. Placed at the end of the power steering hose, it gets compressed against the adjoining surface upon installation, creating a reliable seal that prevents hydraulic fluid from leaking out.

Without a proper seal, the system may experience a loss of steering assistance which could lead to damage over time. Designed to endure the demanding pressures and temperatures associated with power steering, these O-rings are also resistant to degradation caused by contact with power steering fluid and various chemicals.
