## 🔌 Function

The O-ring sits in a groove and is compressed on assembly, deforming to fill the gap between two mating surfaces and block leakage. Its elasticity is what maintains sealing contact as pressure and temperature vary.

## ⚠️ Common Signs of Failure

-   Fluid weeping, seeping or dripping at the joint
-   Hardening, cracking or loss of elasticity on removal
-   Flattening or permanent set so the ring no longer springs back
-   Swelling or chemical attack from the fluid it seals
-   Nicks, cuts or twisting from incorrect installation

## 🛠️ Service Notes

-   Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
-   Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
-   Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
-   Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
-   Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
