# 21541399 Sealing Ring | Genuine Volvo Penta Part

## 🔧 Product Description

A sealing ring used in the crankcase ventilation system of Volvo Penta TAD11 industrial engines. It seals the ventilation hose, separator or adapter joint against oil mist and crankcase-pressure leakage.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD1180-83VE
-   Volvo Penta TAD1170-72VE
-   Volvo Penta TAD1150-52VE
-   Volvo Penta TAD1140-42VE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Genuine Volvo Penta crankcase-ventilation seal
-   Oil- and vapour-resistant elastomer
-   Correct compressed profile for the original connection
-   Suitable for the full TAD11 VE engine range listed below
-   Replace whenever the ventilation joint is separated
-   Engine type: 10.8 L inline-six turbocharged common-rail industrial diesel

## 🔌 Function

Seals the crankcase ventilation connection so blow-by gas follows the intended separator path without oil-mist leakage.

## ⚠️ Common Signs of Failure

-   Oil mist around the breather connection
-   External oil leakage
-   Seal flattening, splitting or hardening
-   Ventilation hose no longer seating securely

## 🛠️ Service Notes

-   Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
-   Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
-   Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
-   Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
-   Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
