Back-up Ring XSBUR08

Function:
Back-up rings do not have a sealing function. They are designed to prevent elastic sealing elements such als O-Rings or Quad Rings of gap extrusion.

Features:
  • Normally cut at an angle for easy installation, but also available as non-split version.
  • Low dynamic friction.
  • Low break-away forces after long standstills.
  • Activated back-up rings reduce gap extrusion and prevent twisiting of the seal in the groove.
