Cometic MLS gasket are compromised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it's ability to rebound, and its 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 environments, load conditions and surface finishes.
The Viton coating is heat resistant to 250°C or 482°F. The center or shim layer of the gasket is compromised of an uncoated stainless steel layer, which varies in thicknesses to meet the needed requirements. MLS gaskets are ideal for both aluminium heads to cast iron blocks as well as aluminium head to aluminium blocks. They can withstand the shearing force created by the two materials. The composition of MLS will also withstand the shearing forces created by aluminium heads on cast iron blocks.
No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
