Parker’s CC profile, also known as the ChemCast™ seal, is a
bi-directional piston seal designed for heavy duty applications. The
CC profile design consists of a self-lubricated, glass reinforced, heatstabilized,
thermoplastic O.D. sealing ring that is energized by a flexible,
oval shape, energizer. When installed in the bore, the precision step cut
ring is aligned and compressed to provide drift free operation that can
withstand pressure exceeding 50,000 psi. The hard thermoplastic cap
allows the CC profile to work effectively in substandard, rough-surfaced
cylinders with much lower tolerances. The CC is an excellent choice for
mobile equipment experiencing shock loads. The CC profile can pass
over ports, resist cold flow and protect against metal-to-metal contact.
The CC profile is sold only as an assembly (seal and energizer). See
part number nomenclature in the downloadable PDF.
