In many applications, back up rings are used to prevent the gap extrusion of the seals or O rings. 

Backup rings perform well in extreme conditions including:

  • High temperatures
  • Increased pressure
  • Larger extrusion gaps 

Our backup rings can be made to suit any application and in any shape or size. Below is a selection of six profiles which can withstand an extreme range of temperatures, making them well-suited to many different industrial applications.
