# 991171 Hose Nipple | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta hose nipple weighing 0.05 kg and listed for 28 applications across the D series — the same fitment count and the same series as 991128, which is published at 0.045 kg. No bore, thread or spigot dimension is given for either, and 5 grams is not a difference a customer can work with, so order by part number rather than trying to tell the two apart.

## 🚤 Compatibility

-   **Engine Family:** D
-   **HP Range:** 145-480 HP

Full model list at the end of this description.
