Cometic Gasket

In only 17 years Cometic Gasket, Inc. has grown into a leading worldwide supplier of custom and short-run gaskets for the motorsports industry. What originally began in 1989, in a 1200 square foot office with limited production facilities, has transformed to a 40,000 square foot state-of-the-art manufacturing center, located in the heart of the Midwest. Today, Cometic produces and ships more than 5,000 types of gaskets to customers throughout the United States, Europe, Canada, Australia, New Zealand, and Japan.

Since its inception, Cometic Gasket has been committed to producing superior quality gaskets for the hi-performance motorsports market. We believe that customer satisfaction comes from close relationships with customers and attention to detail; these remain as our guiding principles to this day.

To ensure superior performance across a wide variety of engine types and sizes, we manufacture our gaskets from a wide range of materials. Whether the situation calls for the latest in advanced technology like our MLS (Multi-Layer Steel) gasket, or a synthetic blend such as our Aramid Fiber, Cometic has the answer.

We combine these advanced materials with state-of-the-art manufacturing processes to provide custom-tailored solutions to meet the needs of each individual customer. Our design engineers have the ability to analyze the environment the gasket will perform in, select the proper material, and apply the appropriate technology to offer the highest performing gaskets available on the market.

Our involvement in motorsports racing led to the development of breakthrough technologies which are now applied to every gasket we build. Cometic Gasket’s involvement in racing circuits such as AMA, ARCA, Busch, IHRA, IRL, NASCAR and the NHRA, have allowed us to develop gaskets that are proven in the most demanding conditions there are- the racetrack.
