Cometic Gasket - Sealed Under Extreme Pressure

Founded in 1989 by Bob Gorman, Cometic Gasket, Inc. began as a small, family-led operation in Concord, Ohio, producing custom gaskets for powersports engines. Today, the company has grown into a 70,000 ft², ISO-grade facility that manufactures over 85,000 gasket SKUs—supply­ing both shelf-stock and short-run, precision sealing solutions for automotive, V-Twin, marine, industrial, and OEM markets.

Cometic pioneered multi-layer steel (MLS) head gaskets engineered with embossed stainless-steel layers and Viton rubber coatings, designed to withstand extreme heat, high boost, and racing conditions without requiring re-torque. Their commitment to in-house design, laser cutting, dyno testing, and hand inspections ensures race-proven reliability and durability.

Built on strong partnerships with NASCAR, drag racing, and SVRA teams, Cometic’s family-oriented culture emphasizes technical collaboration, customer service, and tailored solutions. Whether sealing a daily driver or a championship racer, Cometic stands for precision, performance, and American manufacturing excellence.
