NBR 90 Contoured Backup Rings

Back up rings are commonly used with O-rings, lip seals, and as reciprocating shaft seals. They are also used for piping connections joining two different materials – typically one flexible and one rigid.

90 shore Nitrile (Buna-N) provides sufficient elasticity to allow stretching over the major diameter of a piston and then snapping back into the gland groove cut into the piston. NBR90 Backup rings offer sufficient hardness to resist extrusion of the softer elastomeric O-ring performing the actual sealing function against the high pressure liquid or gas.
