The Parker CT Profile is a robust design for medium to heavy duty hydraulic piston seal applications. The CT Profile is an excellent choice for sealing mobile hydraulic applications that experience shock loads. The CT profile is a four piece assembly made up of a rubber energizer, PTFE cap and two back up rings. 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. Parker's CT profile is designed to retrofit non-Parker seals of similar design. Available in standard (shown) and narrow cross section.
