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.
Ensure a leak-free primary with this Cometic Evo Sportster primary gasket 5-pack. Engineered as a direct replacement, these gaskets provide a dependable seal across multiple heat cycles, crucial for any V-twin.
