Back-up rings are the most common anti-extrusion devices in dynamic sealing. They provide simple solutions to safely increase system function by positioning a more robust material adjacent to the extrusion gap, taking the seal's place and providing a barrier against high pressures. Back UPS can be used to offset the reduced pressure rating effects of wear rings or to improve seal against pressure spikes, or to ensure seal performance at higher tempertures.
