# 858601 O-Ring | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta O-ring weighing 0.001 kg and listed for 61 applications across MD, TMD, AD, AQAD, D and TAMD series engines. No section size or bore is published for it, so order by part number - an O-ring of the right look from a general kit is very unlikely to be the right size or compound.

## 🚤 Compatibility

-   **Engine Family:** MD, TMD, AD, AQAD, D, TAMD, MS, BB, HS, AQD, KAD, KAMD

Full model list at the end of this description.
