Back-Up Rings are installed alongside O-rings to improve their performance. O-rings often fail due to extrusion into hardware clearance gaps at high pressures. Back-Up rings are installed in between the extrusion gap and the O-ring to prevent failure and improve performance. The products below are split Back-Up Rings offered in Virgin PTFE. Additional materials are available such as filled PTFE blends, PEEK, Nylon and various elastomer materials. Please complete the ‘Can’t Find your Size or Material’ form below to obtain pricing information on alternate materials.
