Cometic H1631SPK040S Head Gasket
Cometic Head Gaskets are developed with the performance
enthusiast in mind. With so many individual requirements for each
motor Cometic offers a number of options to suit your specific
motor and needs.
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.
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.
A perforated steel core with an elastomer surface is ideal for head
gaskets allowing heat to be drawn evenly across the gasket surface
while providing maximum sealing characteristics when exposed to
coolants and oils.
