The Cometic MLS (Multi Layer Steel) head gasket is comprised of three layers of stainless steel. Cometic uses stainless steel for increased strength, it’s ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastometer rubber based material(Viton) designed to meet the demands of a variety of harsh sealing enviroments, load conditions and surface finishes. The Viton coating is heat resistant to 250 Celsius or 482 F.
The center or shim layer of the gasket is comprised of an uncoated Stainless Steel Layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.
