Back Up Rings
The PTFE back up rings are proven components used for sealing both low and high-pressure systems. Any system pushing the pressure limits on an elastomer seal, back-up rings are an inexpensive option to increase seal pressure capabilities or increase radial extrusion gaps behind the seal.
The back-up rings come standard in Virgin PTFE but can be made from any filled PTFE compound to increase the pressure capabilities.
PEEK, POM, and Nylon back up rings are also made.
