DESCRIPTION

This Caterpillar-specific four piece piston seal profile is a robust design for heavy duty hydraulic applications, and is an excellent choice for sealing Caterpillar and other mobile hydraulic applications that experience shock loads. This profile is a four piece assembly made up of a rubber energizer, PTFE cap and two back-up rings. The cap material is 15% Glass – 5% Moly filled PTFE.

In application, fluid pressure forces the rubber energizer to apply increased load against the PTFE cap and back-up rings. This results in increased sealing force against the bore and allows the back-up rings to close off the extrusion gap between the piston and the bore. Once activated by pressure, the back-up rings protect the seal from extruding and keep internal contamination away from the PTFE cap.

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