⚙️ Key Features

• 0.007 kg
• 53 applications across TAMD, AD, D, TMD, TD and MD engines

🔌 Function

Seals a joint by being squeezed into its groove, so the trapped rubber blocks the leak path.

⚠️ Common Signs of Failure

• Weeping joint that gets worse with heat and pressure
• Ring found hardened, swollen or squared off on removal
• Nipped or extruded ring where it has been forced past a shoulder
• Groove corroded or scored, so the ring cannot seal

🛠️ Service Notes

• Lubricate the ring lightly before assembly and never twist it into place dry
• Stud 838732 and sealing ring 838896 cover the same 53 applications, so they are often needed for the same job

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
