Founded by Bob Gorman in 1989, the Cometic brand is recognized worldwide as a leader in the design and manufacture of reinforced head gaskets. These, like all of the brand's products, are made in the United States. Cometic reinforced head gaskets consist of several stamped stainless steel sheets held together by rivets. There are three types of Cometic cylinder head gaskets:

MLS: equivalent to MLS Athena gaskets, these multi-layer gaskets (between 3 and 5 sheets of stainless steel depending on the thickness of the gasket) have stampings around the cylinders and fluid passages.

• MLX: this gasket has an identical base to the MLS gasket but a reinforcement (folded sheet) at the level of the cylinders and a special high temperature coating are added.

• HP: this is an MLX gasket on which an additional layer has been added whose aim is to reinforce the sealing of the cylinders (see below)
