# 960629 Plug | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta plug with an M12 thread, 12 mm long, weighing 0.029 kg and listed for 48 applications including D, AD, TMD, TAMD, KAMD and KAD series engines. It supersedes 838743, 838744 and 22813350, one of which was catalogued earlier as a tube — so an old reference may not read like a plug at all. The thread size is the ordering guide here: 960631 is the M16 x 12 mm plug and 960633 is the M20.

## 🚤 Compatibility

-   **Engine Family:** D, AD, TMD, TAMD, KAMD, KAD
