# 3856382 Retaining Ring | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta retaining ring for the PJX water jet units, weighing 0.025 kg and listed for 3 applications. Two more retaining rings sit in the same units — 3856466 at 0.008 kg and 3856470 at 0.005 kg — and this is the heaviest of the three, so all three must be ordered by number.

-   **Engine Family:** PJX
