O-Ring for the power steering hydraulic circuit, sealing a union on the 6mm power steering pipe.

The O-ring seats at the connection between the power steering pipe and its mating component and seals the joint against the pressurised hydraulic fluid, preventing leaks. It is renewed whenever the union is disconnected, as the seal takes a set in service and should not be reused.

Frequently asked questions

What is the Power Steering O-Ring (RTC4825) and what does it do?

The Power Steering O-Ring seals the union on the 6mm power steering pipe where it connects to its mating component. It seals the joint against pressurised hydraulic fluid to prevent leaks in the power steering circuit.

Can the O-ring be reused?

Renew this O-ring whenever the union is disconnected. The seal takes a set in service, so a used one typically won't seal reliably again and can weep under pressure. Fitting a new O-ring each time you open the joint is the safe approach.

Which models does it fit?

This O-ring fits the power steering pipe union on the Land Rover Defender (1987-2006), Discovery 1 (1989-1998, VIN FA393361 to WA799999) and Range Rover Classic (1986-1994). Check your VIN against the listed breaks on the Discovery and Range Rover Classic.

What size pipe does it suit?

It seals the 6mm power steering pipe union, so it's specific to that pipe size and connection. Have power steering fluid ready to top up after fitting, as some loss is normal when the union is opened, then bleed the system by turning the steering after refilling.
