## ⚙️ Key Features

-   OEM separator connection nipple
-   Used in Volvo and Mack crankcase ventilation assemblies
-   Also catalogued for selected Volvo Penta D16 generator separators
-   Supplied as a complete sealed connection assembly
-   Same OEM number used by Mack
-   Engine type: Volvo D13 / D16 and Mack MP8 crankcase ventilation system

## 📋 Kit Contents

-   1 x nipple / connection assembly 20586428
-   Integrated sealing and retaining pieces are supplied within the assembly and do not have separate public Volvo service numbers

## 🔌 Function

Provides the sealed hose or pipe connection at the crankcase separator so vapour and separated oil are routed without leakage.

## ⚠️ Common Signs of Failure

-   Oil mist or liquid oil leaks at the separator connection
-   Nipple is cracked, loose or corroded
-   Hose connection will not remain secure
-   Internal seal is hardened or damaged
-   Crankcase ventilation flow is restricted by contamination

## 🛠️ Service Notes

-   Renew the seal at the connection point when fitting — this is supplied as a complete sealed nipple assembly, not a bare nipple, so the sealing element comes with it
-   Same OEM number is used by Mack for the shared D13 crankcase-ventilation circuit and is separately catalogued against D16 generator separators — confirm which separator housing you are actually working on before ordering
-   Inspect the hose or pipe stub that mates to the nipple for hardening or cracking, since this is the vapour/oil connection point most exposed to heat cycling on the separator
