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.

The Cometic Twin Cam Inspection/Derby Cover Gasket is an essential replacement for your Big Twin V-twin engine. Designed to OEM specifications, this gasket ensures a tight, leak-free seal for your inspection cover, preventing unsightly oil weeping. It's a straightforward replacement that maintains the integrity of your primary system.

Perfect gaskets for your ride ...

You cannot go wrong with Cometic gaskets for your Harley Davidson, in my opinion. Construction materials are top notch, fit and finish are exact, and will provide long gasket life even on our air cooled engines. They may cost slightly more than other aftermarket offerings, however the excellent quality, superb fit and reliable performance make Cometic Gaskets my gasket of choice. I believe you even save money relative to OEM replacements, and quality is as good, or better, IMHO. and I've been riding and building HDs for 50 years, doing my own work.

Does what it’s supposed to do. No leaks when you torque derby cover back on to 95<br />inch pounds.
