Description
ChemCast piston seals provide flawless
sealing at temperatures over 300°F and
pressures exceeding 50,000 psi. They
eliminate hydraulic piston drift, cold flow,
and metal-to-metal contact.
The ChemCast piston ring is made
of reinforced thermoplastic material,
molded into a sturdy, hard, non-porous,
permanently lubricated seal. It is extremely
adaptable to wide pressure and
temperature ranges, and rugged enough
to operate in cylinder bores with substandard
surfaces between 8 and 32aa.
The innovative joint seal (upper photo)
allows pressure application from either side,
making a single ring completely effective in
single or double-acting cylinders.
Parker now makes it easy to use our

Center that can be purchased in quantities
