# 9998491 Nipple | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta nipple 9998491, listed at 0.05 kg, a small connecting fitting from the Volvo Penta workshop tooling range, ordered against the number quoted in the procedure.

## ⚙️ Key Features

-   0.05 kg
-   Threaded connecting fitting for service tooling
-   Genuine Volvo Penta service tooling
-   Ordered by part number

## 🔌 Function

Provides the threaded connecting point between the tool or hose and the fitting it attaches to, so the joint can be made up and sealed.

## ⚠️ Common Signs of Failure

-   Weeping at the joint once pressure is applied
-   Thread worn, damaged or cross-threaded
-   Sealing face scored or bruised
-   Corrosion in the bore or on the threads

## 🛠️ 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
