## 🔧 Product Description

## ⚙️ Key Features

-   Hollow screw from the Cooling System group
-   0.042 kg
-   Supersedes 993241 and covers its 15 TAD series engine applications
-   Drilled through the centre to pass fluid

## 🔌 Function

Clamps a banjo fitting or similar connection to its housing while carrying the fluid through its own drilled centre, so the joint is both a fastener and a passage.

## ⚠️ Common Signs of Failure

-   Weep or drip at the banjo joint that returns after tightening
-   Restricted flow or a temperature difference across the fitting
-   Bore found blocked with scale, sealant or debris
-   Sealing washers found flattened, hard or dug in
-   Thread stretched, stripped or picked up on removal

## 🛠️ Service Notes

-   Renew the sealing washers on both sides of the banjo whenever the joint is broken
-   Check the through bore is clear before fitting - a blocked screw looks like a failed component downstream
