10K – Product Data
Chesterton® 10K seals are
individually molded rod and
piston mounted U-Cups
which provide excellent
performance in both
HYDRAULIC and
PNEUMATIC applications.
■ Super Monoseals
provide an optimal
amount of radial
sealing load to provide
sealing with minimal
frictional resistance.
This results in equipment
that runs smoothly
with longer seal life.
■ Sizes up to 70 inches
(1778 mm ) are available
in 95A Super Polymer
through our fusion
program.
■ 95A Super Polymer
is recognized as the
best overall seal
material that can be
used in the majority
of situations.
Other materials available
to meet specific
requirements.
