O-rings and sealing washers

The small rings and washers sealing sensors, unions, injectors and drain plugs.

Worth knowing before you buy

  • Almost all single-use. A copper sump washer reused is the reason a fresh oil change drips.
  • Cheap enough to order spares with any job, and the usual reason a job stops for a day.
  • Material matters — a generic O-ring in a fuel or coolant application swells and fails.

What we need to quote it. What it seals, and the engine code. The chassis number settles the generation, the body and usually the engine in seventeen characters — it is on your mulkiya. A photograph of the old part helps where there is more than one version.
