⚙️ Key Features

• 0.011 kg
• 169 applications across six engine families
• Quantity varies by assembly, most commonly one

🔌 Function

Seals a static joint between two machined faces or into a groove, holding pressure once the assembly is pulled together.

⚠️ Common Signs of Failure

• Weeping or dripping from the joint the ring seals
• Ring gone hard, squared off or taken a permanent set
• Cracking or splitting on the ring surface
• Nipped or trapped ring, showing a witness mark where it was pinched on assembly

🛠️ 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
