Chesterton 9K Backup Ring
Improve MTBR by Preventing Extrusion Under Pressure

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 9K Backup Ring is created via a machining process which enables ring production of all sizes, made to equipment dimensions. The rings are available in various extrusion-resistant materials and are located on the backside or low-pressure side of the sealing element they are supporting.

Anti-extrusion rings are available in many materials and custom profiles including rectangular, contoured, continuous, or split designs.​​​​​​​​​​​​​

Prevent extrusion of sealing element into equipment clearances; improve MTBR
Static and dynamic applications; plant-wide usage
Available in various profiles and materials
