Full model list at the end of this description.

## ⚙️ Key Features

-   202 applications across the MD, TMD, MB, AQ, AQD and AD series
-   Common closing plug across the older marine range
-   Fits a wide spread of installations
-   Standard replacement item

## 🔌 Function

Closes off a drilled or tapped opening so the passage behind it holds pressure or fluid.

## ⚠️ Common Signs of Failure

-   Weeping, dripping or seeping around the plug
-   Plug head rounded off or burred from a poor-fitting tool
-   Thread stripped or cross-threaded in the housing
-   Sealing washer missing, flattened or hardened
-   Corrosion locking the plug in place so it will not shift

## 🛠️ Service Notes

-   Fit a new sealing washer where the plug uses one, and clean the thread before assembly
-   Do not overtighten into an alloy housing — a stripped thread turns a small job into a repair

## 📦 Condition

-   Genuine Volvo Penta part
-   Brand new
