Full model list at the end of this description.

## ⚙️ Key Features

-   Connection pipe, 0.032 kg
-   Listed for 78 applications across D, TAD and TWD engines
-   Supersedes 20786034
-   Shares its 0.032 kg weight and 78-application count with connection pipe 21021925, which supersedes 20451178 instead

## 🔌 Function

Carries oil or coolant between two housings, its formed ends locating the joint so the seals sit square.

## ⚠️ Common Signs of Failure

-   Wet film or drips at either end fitting
-   Oil pressure or coolant level falling with no obvious external cause
-   Pipe chafed, kinked or fretted where it passes a bracket
-   Corrosion pinholes, often hidden under a clip
-   Sealing ends scored so a new seal will not hold

## 🛠️ Service Notes

-   Connection pipe 21021925 carries the same weight and application count against a different superseded number, so order by part number rather than by comparing the two
-   Renew the o-rings or seals at both ends whenever the pipe is disturbed
