Back-up rings are also known as anti-extrusion rings since their main function is to prevent o-rings from entering the clearance gaps due to internal pressure. They avoid the seal from experiencing premature failure.
Backup rings are not seals themselves, but are used in conjunction with O-rings or other seals in high-pressure applications. Backup rings are installed in the downstream side of the gland, however, can be installed either side of the O-ring to give a high-performance double-acting seal.
Back-up rings come in a variety of materials such as: PTFE, filled PTFE, PEEK.

Spiral Wound PTFE Back-up Rings Advantages & Application
When used for relevant purposes under appropriate conditions, industrial PTFE backup rings provide various applicable benefits. PTFE backup rings are built in such a way that they can be used to prevent extrusion in rubber sealing systems.
O-rings are used in hydraulic and pneumatic systems to provide excellent sealing solutions in dynamic and static applications. However, when subjected to high temperatures and pressures, O-rings extrude into the clearance between mating surfaces.
Elevation in ambient pressure or temperature places a significant strain on the physical and chemical qualities of the rubber O-rings, causing the rings to extrude farther and eventually fail and leak.
