## ⚙️ Key Features

-   5 mm high
-   0.009 kg
-   Supersedes 21111085
-   37 applications on D series engines

## 🔌 Function

Seals a static joint between two mating parts, holding fluid or pressure on the correct side of the face.

## ⚠️ Common Signs of Failure

-   A damp film or slow drip at the joint the ring seals
-   Ring squared off on section rather than round when removed
-   Splits, nicks or a spiral twist along the ring
-   Rubber gone hard and brittle, or swollen and soft
-   Fluid or pressure loss with no other visible source

## 🛠️ Service Notes

-   The 5 mm section height is the distinguishing detail on this row, so measure the ring you removed - 994421 is the other o-ring in this group, published at 0.007 kg, and is not a substitute
-   Clean the groove back to bare metal and fit the ring dry or lightly lubricated as the assembly requires; old sealant in the groove holds the new ring off its seat
