Description

Back-up rings (aka anti-extrusion rings) are used in conjuction with o-rings and work to protect them and help prevent extrusion in high pressure applications. This works by closing the clearance gap and reducing friction by trapping lubricant in the area of the seal.

Single acting applications (single sided pressure) where only one back-up ring is required, the back-up is located on the low pressure side of the o-ring; although it is often recommended that two back-ups be used in single acting applications to mitigate the possibility of installing the back-up on the wrong side of the o’ring.

Double acting applications (using bi-directional pressure) require the use of two back-up rings, one on either side of the o-ring.
