MLS (Multi Layer Steel)
The Cometic MLS gasket is comprised of three layers of
Stainless Steel. Cometic uses Stainless steel for increased
strength, it’s ability to rebound and corrosion resistance. The
outer layers of the gasket are embossed and coated on both
sides with a flouroelastomer 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 2500C or 4820F.
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 both aluminum heads to cast iron blocks and
aluminum heads to aluminum blocks.
Gasket Materials
The composition of MLS will also withstand the shearing forces created by aluminum 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.

  • Head Gasket Torque Procedure - If you are using studs or head bolts, torque hardware to the manufacturers specification. Fasteners works like a springs and must have proper Torque or Stretch applied to carry the correct amount of clamp force. Also use the proper lube or thread sealer for the job. All fasteners must be final torqued before thread sealant cures to achieve proper torque.
    Torque the fasteners in the correct sequence. It is critical to follow manufacturers torque sequence to apply clamp force evenly. A smooth continuous motion is important for every torque sequence. Re-torque is not necessary unless using hardware that has not been heat cycled.
