Backup Rings prevent extrusion of O Rings In high pressures usually above 1500 PSI & compensate for loose fitting components.

If only one backup ring is used, the O Ring should be placed between the pressure source & the backup ring.

One backup ring should be used on each side of the O Ring in double acting assemblies if possible two backups should be used even in single acting assemblies.

 
Construction Materials
Anti Extrusion Back Up Rings are Manufactured from over 15 different Polymers which include. Nitrile (NBR), Fluorocarbon (Viton®), Silicon (VMQ), Fluorosilicone (FVMQ), Polyurethane, PTFE (®), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (H-NBR), Carboxylated Nitrile Rubber(X-NBR), Styrene Butadiene Rubber (SBR), Perfluoroelastomer (FFKM), Chloroprene (Neoprene®).
