-   Nicks or a spiral twist from careless assembly
-   Ring swollen or gone sticky from the wrong fluid
-   Joint leaking again shortly after being retightened

## 🛠️ Service Notes

-   Always fit a new O-ring rather than reusing one, and lubricate it before assembly
-   Check the groove and lead-in chamfer for burrs that would cut the new ring
