MLS (Multi Layer Steel)
The Cometic MLS gasket is comprised of three to five layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a Viton rubber material designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 250C or 482F.
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 any kind of head and block combination. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
