Cometic Engine Gasket Set

Cometic Engine Gasket Sets: Race-Proven Sealing for Every Build

When an engine rebuild demands nothing less than a perfect seal, Cometic Gasket is the name serious engine builders reach for. Engine gasket sets from Cometic aren't simply a collection of parts — they are precisely engineered sealing systems built on decades of motorsports expertise. Founded in 1989 and headquartered in a 70,000-square-foot manufacturing facility in Concord, Ohio, Cometic has grown from a powersports specialist into a globally recognized supplier trusted across NASCAR, NHRA, IHRA, and countless amateur racing programs.

What Sets Cometic Engine Gasket Sets Apart

The core of Cometic's advantage lies in its material science and engineering discipline. Rather than applying a one-size-fits-all approach, Cometic engineers analyze the specific environment a gasket must perform in, select the proper material, and apply the appropriate technology for each application. This results in gasket sets that are custom-tailored rather than generic.

Cometic's engine gasket sets draw from a broad material portfolio, including:

• MLS (Multi-Layer Steel): Multiple embossed layers of proprietary high-temperature-coated and uncoated stainless steel with AMP (Advanced Multi-Polymer Coating), offering superior load distribution and reduced bore distortion.
• MLX (Multi-Layer Xtreme): Builds on the MLS design with an integrated "stopper" layer engineered to enhance clamp load around the cylinder bore without increasing bore distortion — ideal for high-boost and forced-induction builds.
• Aramid Fiber: A synthetic blend chosen for its fluid resistance and sealability across a wide range of temperatures and environments.
• EST (Embossed Stainless Technology): Used in critical sealing surfaces such as rocker box and cylinder base gaskets within complete engine kits.
• Reinforced Compounds: Including armor-clad, graphite, and galvanized steel, constructed specifically for sealing irregular or worn surfaces.
