## ⚠️ Common Signs of Failure

-   Air hissing at the hose stem under pressure
-   Hose creeping off or blowing off the nipple
-   Weak or slow cranking through lost starting air
-   Hose stem corroded, scored or the sealing shoulder damaged
-   Bore found restricted by corrosion or scale on strip-down

## 🛠️ Service Notes
