🔌 Function

The sealing ring forms a static seal between two mating components to contain fluid or gas and prevent leakage at the joint. As the upper item, it seats at the top position of its assembly and works together with the corresponding lower ring.

⚠️ Common Signs of Failure

• Visible fluid seepage or drips around the sealed joint
• Hardened, cracked or brittle ring material on inspection
• Flattened, distorted or extruded ring that no longer holds its cross-section
• Loss of system pressure or air ingress at the sealed connection
• Staining or residue tracks below the joint indicating a slow weeping leak

🛠️ 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
