Cometic's MLS gaskets utilize multiple layers of stainless steel with integrated sealing technologies to create a gasket that recovers from thermal expansion and contraction, ensuring a reliable seal throughout the engine's operating range. The embossed layers provide concentrated sealing pressure around combustion chambers, water jackets, and oil passages.
