The PTFE Back-Up Ring (Part No. 89150106) is designed to prevent O-ring extrusion in high-pressure sealing applications. Manufactured from high-quality PTFE, this back-up ring offers excellent resistance to chemicals, temperature extremes, and wear, making it ideal for demanding industrial and hydraulic systems.

The cut (split) design allows for easy installation without disassembling hardware, while the precise dimensions ensure effective support for O-rings operating under pressure.
