Cometic Gasket — MLS Head Gaskets & Engine Seals

Cometic Gasket produces precision-machined engine sealing components used by professional engine builders and race teams worldwide. MLS head gaskets, intake gaskets, and complete engine gasket sets from Cometic are engineered to hold seal under the elevated cylinder pressure and heat cycling that OEM gaskets cannot always survive in high-performance applications.

Popular Upgrades

Cometic MLS (multi-layer steel) head gaskets are the most-requested upgrade for turbocharged, supercharged, and naturally aspirated builds where cylinder pressure exceeds the limits of OEM composite gaskets. Available in bore sizes and thicknesses calibrated to manage compression ratio, Cometic MLS head gaskets are a standard specification for any serious engine build. Intake manifold gaskets, exhaust gaskets, and cam cover sets round out the range for complete engine assembly work.

Why use Cometic MLS head gaskets over OEM?

Cometic MLS head gaskets use multiple layers of embossed stainless steel that create a spring-loaded sealing effect around each combustion chamber. This design withstands repeated pressure pulses from high-boost or high-compression combustion events that would blow out or crush a standard graphite or composite gasket over time. For any engine making more than stock power on boost or nitrous, MLS is the reliable standard.

Does Cometic make gaskets for diesel engines?

Yes. Cometic produces head gaskets and engine sealing components for Duramax, Cummins, and Power Stroke diesel platforms alongside their gasoline performance catalog. Diesel-specific MLS head gaskets are designed to handle the extreme cylinder pressures generated by high-boost diesel builds and are popular with Duramax and Cummins performance builders seeking alternatives to OEM head gaskets.
