Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally-aspirated, boosted, or nitrous-fed engines. The head gaskets are made from 3-5 layers of spring stainless steel, offering a stronger base material than standard cylinder head gaskets. Viton-coated stainless steel outer layers create a superior seal not available with other steel or copper gaskets. MLS Gaskets reduce bore distortion, resist corrosive substances, and have excellent rebound qualities. Sold individually.
Features
Made from stainless spring steel for exceptional corrosion resistance
Designed to withstand serious cylinder pressures without machining for installation of locking wire
MLS Cylinder Head Gaskets are coated with .001" thick Viton rubber that's bonded to the outer stainless steel layers
Installation Notes
Not designed for use on engines with O-rings or receiver grooves
Always refer to the fastener manufacturer to determine accurate torque values
A surface finish of 50 RA (roughness average) or finer is recommended for proper gasket seal
Cometic Cylinder Head Gaskets go on dry because they're coated with a sealant (adding another sealer can hinder gasket performance)
