Advanced MLS Technology:

Cometic's MLS head gaskets utilize multiple layers of stainless steel with a Viton rubber coating on the outer layers. This design provides exceptional recovery and sealing properties, conforming to minor surface imperfections while maintaining superior combustion seal integrity. The MLS construction allows the gasket to handle higher cylinder pressures and temperatures compared to traditional composite gaskets, making it suitable for both naturally aspirated and forced induction builds.

Each Cometic gasket is manufactured in the USA using proprietary materials and processes developed through extensive motorsports experience. The gasket's stopper layer controls thickness and provides rigidity around the combustion chamber, while the soft outer layers ensure proper sealing on the deck surface and head face.
