Back-UPRing ( Part A) The Polyacetal back ring should save the PTFE part against extrusion and protect the sealing systemagainst dirty pieces. Slide Ring Dynamic (Part B) Slide ring section is retangular and has been produced for years from PTFE - bronze compound. The Slide ring shows a high abrasion resistance, inherent stability and additional good extrusion resistance. These properties make the material suitable for the demands of heavy-duty hydraulics and construction industry. Additional we are supporting a special slide ring of Polyurethane for low and middle pressure applications. Rubber Energizer (Part C) During the total period of compression the T-formed NBR energizer guarantees reli- able radial pressure to the dynamic seal. For applications with additional areas of tem- peratures there are various materials available. 70 A B C Piston Seal GHT
