BACK UP RINGS

Backup RINGs, which are a piece of O-ring holder and are used at high pressure, are placed on the O-rings in both static and dynamic states and prevent them from corrosion. Usually the backup difficulty should be higher than the O-ring difficulty.

Backup rings generally have a rectangular cross section and are made in various shapes and forms. Backup rings must be machined to a very precise tolerance to prevent elastomeric gaskets such as polyurethane from protruding.

 

Advantages of backup ring usage:

  • Concave cross section
  • Use of NBR and VITON materials
  • Enabling reciprocal movements in floods
  • Prevent O-ring deformation and flood protection
  • Improve sealing pressure and increase flood service life
