Anti Extrusion Back Up Rings
 

Backup rings prevent extrusion "O" rings In high pressures usually above 1500 PSI & compensate for loose fitting components.
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.
If only one backup ring is used, the "o rings should be placed between the pressure source & the backup ring.
Contact us for more information on backup rings.
