21246687 O-Ring | Genuine Volvo Penta Part

🔧 Product Description

Genuine elastomer sealing ring used in designated Volvo Penta engine and equipment assemblies. It provides a pressure-tight seal between accurately machined mating components.

⚙️ Key Features

• Genuine Volvo Penta sealing ring
• Correct OEM material and dimensions
• Resistant to the fluid specified for its installation
• Designed for controlled groove compression
• Suitable for marine and industrial engine use

🔌 Function

The O-ring prevents fluid, air or pressure leakage between the two mating components.

⚠️ Common Signs of Failure

• Flattened or hardened sealing ring
• Cuts or nicks
• Swelling caused by incompatible fluid
• Leakage after the joint has been disturbed

🛠️ Service Notes

• Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
• Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
• Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
• Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
• Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
