Founded by Bob Gorman in 1989, the Cometic brand is recognised 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 are made up of several pressed stainless steel sheets held together by rivets. There are three types of Cometic cylinder head gasket:

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

• MLX: this gasket has the same base as the MLS gasket, but a reinforcement (folded sheet) around the cylinders and a special high temperature coating are added.

• HP: this is an MLX gasket to which an additional layer has been added, in order to reinforce the sealing of the cylinders (see below).
