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.
When servicing your Milwaukee-Eight Softail's primary, a fresh, reliable gasket is crucial for preventing leaks. This Cometic primary housing gasket is engineered with Advanced Fiber Material (AFM) technology to provide a robust seal.

Gaskets for your Harley Davidson - Cometic brand
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.

My last primary gasket was a well know brand that weeped slightly along the bottom edge, enough for dirt to stick. Also the edge of the gasket protruded beyond the case. <br />The Cometic gasket is perfectly flush with the case and no weeping. Well worth a few extra dollars.
