PERFORMANCE ADVANTAGES
Parker’s CT Profile is a robust design for heavy duty hydraulic applications. IT is an excellent choice for sealing mobile hydraulic cylinders in 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 piston seal will retro-fit non-Parker seals of similar design.

The CT Profile is sold only as an assembly (seal, energizer and back-up rings). The temperature range of the CT profile is limited to the thermal capability of the rubber energizer. A wider temperature range may be achieved by using alternate energizer and back-up ring materials.

Standard Materials
• PTFE, Cap: 0401, 40% bronze-filled PTFE; Temp limited by capability of energizer; Pressure dictated by back-up rings; Surface Speed <5 ft/s)
• Rubber Energizer: 70A Nitrile; Temp -30 / +250F
• Back-up rings: Moly-filled nylon; Temp limited by capability of energizer; Pressure Range 7,500 psi*


*Pressure range shown is for systems without wear rings. If used with wear rings, consult Engineering Section (Section2) of Parker’s Fluid Power Seal Design Guide, Catalog EPS5370.

Alternate Materials: For applications that may require an alternate material, please contact your Parker EPS representative.
