🔌 Function

Seals the joint between two faces, squeezed into its groove to hold pressure and keep fluid where it belongs.

⚠️ Common Signs of Failure

• Weeping or seeping at the sealed joint
• Ring flattened, hardened or shiny
• Nicks or a nibbled edge from assembly
• Swelling from contact with the wrong fluid

🛠️ 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
