## 🚤 Compatibility

-   **Engine Family:** D

Full model list at the end of this description.

## ⚙️ Key Features

-   Machined fuel-system connection fitting
-   Correct thread, shoulder and internal flow diameter
-   Used at the original fuel-filter housing connection
-   Diesel-compatible material and sealing face
-   Nipple only; hose, hollow screw and sealing rings are separate
-   Engine type: Volvo Penta inline six-cylinder marine diesel

## 🔌 Function

Connects the specified fuel line to the filter housing while preserving a sealed, unrestricted diesel passage.

## ⚠️ Common Signs of Failure

-   Diesel seepage at the fitting
-   Damaged or crossed threads
-   Restricted flow from contamination
-   Repeated sealing-ring failure from a damaged seat

## 🛠️ Service Notes

-   Check the bore is clear before fitting — a nipple is often the feed point or restriction for a circuit, and debris left in it will starve whatever it supplies
-   On tapered threads use the paste or liquid sealant specified for the fluid concerned, applied a few threads back from the open end; avoid thread tape on fuel and oil lines, where a shed shred travels downstream into filters, pumps and injectors
-   Where the nipple seals on a face or against a washer rather than on its thread, fit a new sealing washer instead of curing a weep by overtightening
-   Tighten to the figure in the workshop manual for your engine — these are small fittings in castings and are easily stripped, or the surrounding boss cracked
-   Support the pipe or hose so it meets the nipple square and without side load, then check the joint at working pressure and temperature
