Cometic's MLS gaskets are constructed from multiple layers of stainless steel, with each layer serving a specific purpose to create a superior seal. The outer layers are embossed to provide the necessary spring pressure for sealing, while the inner layers add strength and resilience. This design allows the gasket to recover and maintain its seal through repeated heat cycles, making it an excellent choice for both street performance and racing applications.
