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.
Keep your Harley or Indian Twin Cam engine sealed tight with the Cometic Twin Cam O-Ring 10-Pack. These OEM replacement O-rings (OE# 11290) are crucial for maintaining proper sealing and preventing fluid leaks in various applications across your V-twin.
