An o-ring is contained in a gland and forced to flow into the surface imperfections of the glands and any clearance gaps available to it. An o-ring can perform sealing by means of squeeze under low pressure conditions. The extent of extrusion depends upon the hardness of O-ring, the pressure, and the size of the clearance gap.
Parker's KB292-95 compound is formulated to offer best in class resistance to extrusion for the highest of pressure applications. With an operating temperature range of -25°F to 300°F, and chemical compatibility in line with traditional hydrogenated nitrile (HNBR) compounds, KB292-95 truly expands the capabilities of this polymer family.

There are different methods to counter O-ring extrusion. One of these methods is to simply increase the durometer rating of the O-ring. However, as you increase the durometer, the O-ring can become less malleable. Another option would be the use of anti-extrusion devices or back-up rings.

Back-up Rings. Back-up rings are anti-extrusion elements designed to prevent the migration of sealing material into the extrusion gap under the system pressure. They are open or closed shapes for snap assembly made of a wide range of compounds which are highly resistant to thermal or mechanical stress. Back-up Rings Products from parker include.,

With a similar appearance to extrusion, gland overfill failure mode also has the unique, "tails" of O-ring material. The difference is the tails extend out from both corners of the groove, and, if significant, you may see the round O-ring cross section now resembles a square. Learn More
Extrusion and Nibbling . Extrusion and nibbling of the O-ring is a primary cause of seal failure in dynamic applications such as hydraulic rod and piston seals. This form of failure may also be found from time to time in static applications subject to high pressure pulsing which causes the clearance gap of the mating flanges to open and close, trapping the O-ring between the mating surfaces.

The failure mode most frequently associated with high fluid pressure is extrusion. Extrusion is the phenomenon of the O-ring being forced into the clearance gap, rendering damage to the seal and eventual leakage. The amount of pressure the O-ring can withstand is generally a function of the clearance gap and the material selection.
