## 🔌 Function

The sealing ring creates a static seal between two mating surfaces or around a component passing through a housing, preventing fluid or pressure loss at that joint. It compresses on assembly to fill the sealing face and maintain a leak-free connection.

## ⚠️ Common Signs of Failure

-   Visible fluid weeping, dripping or staining around the sealed joint
-   Hardened, cracked or brittle ring material on inspection
-   Flattened, distorted or extruded ring that no longer holds its shape
-   Loss of system pressure or repeated top-ups of the affected fluid
-   Residue or corrosion build-up on the sealing faces indicating a slow 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
