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.
This Cometic Evo O-ring 10-pack is a versatile seal designed for various applications on Harley Sportster and other Evo-platform V-twin engines. It's a direct replacement for the factory O-ring, ensuring a proper seal where needed.
