Abstract
A tubular has an exterior sealing element disposed in a recess. A swage passes through the tubular to increase its drift dimension from a location above the seal to below the seal. The interior projection that initially defined the exterior wall recess where the seal is located is expanded to the new drift dimension of the balance of the tubular. Extending members that are initially embedded in the seal while extending from the tubular wall that defines the recess move out during the expansion to engage the surrounding tubular to act as extrusion barriers and to aid in the fixation of the seal while being able to penetrate the wall of the surrounding tubular in so doing.
