Contoured Back-Ups are routinely produced in a 90 durometer
Nitrile - Buna-N. This provides sufficient elasticity to permit stretching over
the major diameter of a piston and then snapping back into the gland groove
cut into the piston. 90 durometer has sufficient hardness to resist extrusion
of the softer elastomeric O-Ring performing the actual sealing function against
the high pressure liquid or gas.
