BACK-UP

Back-up rings are principally used as anti-extrusion devices in high pressure O-Ring environments. High Performance Seals offers back-up kits in either split PTFE or 90 durometer nitrile contoured back-ups so they accommodate a range of applications.

BACK-UP SPLIT PTFE

Single turn PTFE back-up rings help control O-Ring extrusion in high pressure applications. More
