Cometic C4252-040 Head Gasket

Cometic Head Gasket: Cometic head gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each engine, Cometic offers a number of options to suit your engine and specific needs. *MLS* The Cometic MLS gasket is composed of three layers of stainless steel. Cometic uses stainless steel for increased strength, rebound ability, and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a fluoroelastomer rubber-based material (Viton) designed to meet the demands of a variety of harsh sealing environments, loading conditions, and surface finishes. The Viton coating is heat resistant up to 2500C or 4820F. The center or shim layer of the gasket is composed of an uncoated stainless steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads and cast iron blocks, and aluminum heads and aluminum blocks. The MLS composition will also resist the shear forces created by aluminum heads on cast iron blocks. Retorque is not required. By design, the MLS gasket promotes uniform torque loading across the sealing surface, allowing for measurable reduced bore distortion.
