DESCRIPTION

The MCPS profile is a robust design for heavy duty hydraulic applications. The MCPS is an excellent choice for sealing mobile hydraulic applications that experience shock loads. The MCPS profile is a four piece assembly made up of a rubber energizer, PTFE cap and two back-up rings. Our standard seal material is 15% Glass – 5% Moly filled PTFE. We also supply in 40% Bronze-filled PTFE which is preferred for higher speed applications and improved seal ability.

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.
