                                 PEEK Anti-extrusion rings

Anti-extrusion rings, also known as backup rings, are used in conjunction with o rings in high-pressure applications as this particular type of ring seal provides relative diametrical play and can reduce the level of friction. Back-up rings are used to extend the operating pressure of an O-ring. Either one or two back-up rings are co-located within a groove of increased width, on the low-pressure side of the seal.

Anti-extrusion rings provide added extrusion resistance and prevent damage to O-rings and seals when subjected to high pressures, larger extrusion gaps, and/or high temperatures.

The use of back-up rings can significantly increase the pressure rating of seals.

When we use o rings as seals in applications where pressure levels are high, extrusion of the seal can become a risk factor., the o ring begins to extrude from the housing, causing physical damage to the seal, making the seal no longer fit for purpose.Therefore, an anti-extrusion ring will be required to prevent the o ring from moving and causing extrusion in these instances. Anti-extrusion rings or backup rings are designed to prevent extrusion in rubber or polymer o-ring sealing systems.

PEEK is a semi-crystalline, show high stiffness and hardness, has an unique high tensile strength and With a continuous service temperature of 260 ℃, PEEK is used for backup rings for O-rings under high pressure or as a v-packing support ring or thrust ring.

V závislosti na požadavcích aplikace jsou naše záložní kroužky vyrobeny z PEEK, uhlíkového PEEK, Virin PTFE nebo plněného PTFE.
