⚙️ Key Features

• Genuine Volvo Penta Sealing Ring - part number 20883450
• Exact OEM cross-section and diameter
• Material matched to the relevant oil, coolant, fuel, air or exhaust exposure
• Controlled compression in the original groove
• Maintains sealing through pressure and temperature cycles
• Correct hardness prevents extrusion and excessive friction
• Single-use service item; lubricate only as specified before installation
• Engine type: Application-specific Volvo Penta engine sealing and fluid-control system

🔌 Function

The ring fills the designed clearance between mating components. Compression produces contact pressure around the full circumference, preventing the working fluid or gas from passing through the joint.

⚠️ Common Signs of Failure

• Flattened, hardened or cracked ring
• Ring is cut or twisted during assembly
• Leakage appears after pressure or temperature rises
• Seal extrudes from an incorrect groove or excessive clearance
• Material swells from incompatible fluid

🛠️ 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
