Abstract
An anti-extrusion apparatus for a seal sealing on the outside diameter of a conduit. The anti-extrusion device is positioned at each end of the seal and includes a metal ring engaging an end of the seal in which the ring has a wedge shaped inside. A plurality of arcuate ring segments form a close ring having inner diameter equal to the outside diameter of the conduit. The segments have a wedge shaped outside coacting with the metal ring and are wedged inwardly against the conduit prior to compression of the seal for reducing extrusion of the seal as it is compressed.
