🔌 Function

The sealing ring seals the joint between two mating components so that fluid or pressure cannot escape past the connection. It compresses on assembly to form a tight, conforming barrier at the sealing face.

⚠️ Common Signs of Failure

• Fluid seepage, weeping or drips around the sealed joint
• Hardened, cracked or brittle seal material found on inspection
• Flattened, distorted or extruded ring that no longer holds its shape
• Loss of system pressure or repeated need to top up fluid levels
• Staining or residue tracking down from the joint face

🛠️ Service Notes

• Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
• Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
• Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
• Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
• Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
