Petrochemical PTFE Back Up Rings White Thermoplastic Seals

Backup ring is a high-performance thermoplastic

Back-up Rings have no intended sealing function. Instead, as the name indicates they are supporting elements made with extrusion-resistant materials which generally have a rectangular cross section. They are installed in a groove together with an elastomeric sealing element preferably with a corresponding O-Ring in static applications. Due to the tight fit of the Back-up Ring in the housing, they prevent extrusion of the pressurized elastomeric sealing element into the sealing gap.
