DESCRIPTION

The Caterpillar-specific nylon step-cut 2-piece piston seal is similar to the PS914 profile, also known as the ChemCast seal, and is a bi-directional piston seal designed for heavy duty applications. This seal consists of a self lubricated, glass reinforced, heat stabilized, 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. The hard thermoplastic cap allows this profile to work effectively in substandard, rough-surfaced cylinders with much lower tolerances. This seal is an excellent choice for mobile equipment experiencing shock loads. This profile can pass over ports, resist cold flow and protect against metal-to-metal contact.

This seal is the same as our PS914 profile, but available in Caterpillar-specific sizes.
