## 🔌 Function

## ⚠️ Common Signs of Failure

-   Seeping or a wet film around the joint after running
-   Ring flattened, split or bedded hard into the face
-   Sealing faces scored or picked up
-   Joint needing repeated re-tightening to stay dry

## 🛠️ Service Notes

-   Sealing rings are single use — fit a new one whenever the joint is disturbed
