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 primary gasket is an essential component for maintaining a leak-free primary drive on your Panhead, Shovelhead, or Evolution Big Twin. Engineered for the demands of V-twin performance, it provides a robust seal against oil leaks and weeping.

Common questions
Will this primary gasket fit my Sportster?
No, this Cometic primary gasket is specifically designed for Harley-Davidson Panhead, Shovelhead, and Evolution Big Twin engines. Sportster models use a different primary gasket.
What is the benefit of this Cometic gasket over a factory gasket?
Cometic gaskets are engineered for consistent sealing across a wide range of temperature and pressure cycles, helping to reduce the common weeping often seen with older OEM gaskets.
Do I need to replace the primary gasket every time I open the primary cover?
It's recommended to inspect the gasket carefully. If it is undamaged and can still provide a proper seal when reinstalled, it may be reusable. Always check for tears or permanent compression before deciding to reuse.

A mediocre gasket
I didn’t use this gasket after removing the derby and seeing the Harley gasket that I removed. No comparison in quality. I ended up going to the local dealer and bought an O.E. gasket.

There is nothing on them indicating they are actually Cometic gaskets. Are they Substitutes?
