Backup Rings 

A back up ring prevents extension and extrusion of a packing or an O-ring. Backup Rings are mainly used in combination with O-rings to secure the O-ring so that it is not ejected. The Backup Ring minimizes the gap and thus ensures that the O-ring is not pushed into the gap and damaged.

Backup Rings are economically advantageous sealing elements with a very wide range of applications in pneumatic and hydraulic systems. Backup Rings make it possible to use O-rings under high pressure, and can be used both statically and dynamically

​Backup Rings are used in almost all industries, but especially in stationary machines and for static sealing.

Backup Rings is often made of PU, PTFE or POM.​
