# 21246687 O-Ring | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine elastomer sealing ring used in designated Volvo Penta engine and equipment assemblies. It provides a pressure-tight seal between accurately machined mating components.

## ⚙️ Key Features

-   Genuine Volvo Penta sealing ring
-   Correct OEM material and dimensions
-   Resistant to the fluid specified for its installation
-   Designed for controlled groove compression
-   Suitable for marine and industrial engine use

## 🔌 Function

The O-ring prevents fluid, air or pressure leakage between the two mating components.

## ⚠️ Common Signs of Failure

-   Flattened or hardened sealing ring
-   Cuts or nicks
-   Swelling caused by incompatible fluid
-   Leakage after the joint has been disturbed

## 🛠️ Service Notes

-   Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
-   Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
-   Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
-   Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
-   Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
