Backup Rings

Back-up Rings are used in conjunction with O-Rings for both static and dynamic sealing applications.  Back-up rings prevent extrusion of the o-ring when it is subjected to high pressures.  Back-up rings help when the extrusion gaps are excessive.  Two back-up rings should be used, one on each side of the o-ring, wherever possible.  Back-up rings are washer like devices.  Back-up rings are not seals themselves.  Back-up rings are a support item like a spacer.  Back-up rings are available in two designs, a flat washer style and a contoured style.  Back-up rings may also be called buffer rings.
