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

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

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

• HP: this is an MLX gasket with an additional layer added to further reinforce the sealing of the cylinders (see below).
