Cometic MLS gaskets are comprised of multiple layers of stainless steel due to its increased strength, ability to rebound and resistance to corrosion. The outer layers of the gaskets are embossed and coated on both sides with Viton - a flouroelastomer rubber based material that is heat resistant to 250C / 482F. Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The centre or shim layer is a uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements. They provide maximum sealing performance for today’s high output engines and require no sealants. Ideal for aluminium heads to aluminium blocks and aluminium heads to cast iron blocks withstanding the shearing force created by the two materials. No need to re-torque, the embossing design of the MLS gasket promotes an even clamp load across the sealing surface allowing for measurable reduced bore distortion.

A surface finish of 50 microinches or finer is recommended for a proper gasket seal. Anything rougher may result in gasket failure.
