COMETIC MLS (Multi-Layer Steel) Head Gaskets offer maximum sealing performance for today's high output engines and require no sealants.

Ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, MLS gaskets can withstand the shearing force created by the two materials.

Increased strength is provided by multiple layers of stainless steel, which also creates the ability to rebound and resist corrosion.

The outer layers are embossed and coated on both sides with Viton, a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F.

Designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes, the center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.
