Back-Up Ring S07

s08

DESCRIPTION

Back-up rings are supporting elements with no sealing functions. They have a tight fit in the housing and therefore protect installed sealing elements from extrusion into the sealing gap.

The S07 back-up ring extends O-ring life and allows O-rings to perform in high-pressure applications. It also has a high resistance to applied media, is easy to install, and is available in non-standard sizes.

APPLICATION

Support element for preventing extrusion into the radial sealing gap. Suitable for applications over a wide temperature range from -70 ˚C to +260 ˚C (valid for PTFE material).
