Cometic MLS (multi-layer-steel) Head Gaskets are ideal for
any combination of head and cylinder materials.
Cometic MLS Gaskets are comprised of three layers of Stainless Steel. Stainless
Steel is used for its increased strength, its 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 250 0C 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 Cometic
MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum
heads to aluminum blocks. 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.
