## ⚙️ Key Features

-   Also supplied in the repair kit for the lock valve
-   0.002 kg
-   141 applications across D, TD and TAD series engines and IPS installations

## 📋 Kit Contents

-   Included in repair kit for lock valve., (925053)

## 🔌 Function

Seals a hydraulic joint in the lock valve, holding pressure so the circuit stays where it is set.

## ⚠️ Common Signs of Failure

-   Hydraulic weep or a wet film around the valve
-   Circuit creeping or drifting away from its set position
-   Ring flattened, hardened or nicked on removal
-   Fluid level falling with no obvious external leak
-   Seal swollen or softened by the wrong fluid

## 🛠️ Service Notes

-   If the lock valve is being overhauled, order the repair kit rather than the single ring
-   Renew every seal in the valve at once — replacing one and leaving the rest usually means a second strip-down
-   Check the bore and groove for scoring before refitting
