The
Cometic
MLS
(Multi
Layer
Steel)
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
materioal
(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
degrees
Celcius
or
482
degrees
farenheit.
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.

is
the
