# 859725 Plug | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta plug from the Engine group, weighing 0.025 kg and listed for 7 applications across the TMD, TAMD and MD series. It supersedes 859816, which was catalogued earlier as a connector — so paperwork listing 859816 as a connector now resolves to this plug.

-   7 applications across the TMD, TAMD and MD series
-   Supersedes 859816, catalogued earlier as a connector
-   Engine group

## 🔌 Function

Closes off a drilling or port in the engine so the passage behind it stays sealed and holds pressure.

## ⚠️ Common Signs of Failure

-   Weeping or a damp trace around the plug
-   Sealing face pitted or the seat corroded
-   Plug loose, backed out or missing
-   Pressure lost from the passage the plug closes

## 🛠️ Service Notes

-   Because 859816 was listed as a connector, an old parts list may describe this position differently from what arrives — check the fitting against the engine before condemning the supply
-   Clean the seat and fit a new plug rather than reusing the old one
