About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
Prevent oil seepage at a critical junction in your Milwaukee-Eight engine with this Cometic cam housing to oil pump O-ring seal. Engineered as a direct replacement, this 10-pack ensures you have spares on hand for future service or multiple builds. Riders trust Cometic for their quality and precision in sealing performance.

When you're wrenching on a Milwaukee-Eight, every seal matters. This Cometic O-ring provides a reliable, direct replacement for the cam housing to oil pump interface, a common area for potential leaks if not sealed correctly.

Essential for Engine Health
Maintaining a tight seal around your engine's critical components is non-negotiable for performance and longevity. This O-ring is a small but vital part of that system.

Don't let a minor leak turn into a major problem – seal it right with Cometic.

I ordered an extra O-ring for Crank shaft position sensor "just-in case". Part matches.
