Abstract
A mandrel bladder end fitting includes a compression housing defining a circumferential interior wall; the interior wall constitutes a first clamping surface. An expansion assembly, axially received within the interior wall, includes a plurality of wedges that collectively define a second clamping surface. The expansion assembly also includes a central core and a threaded member received within a threaded aperture of the central core. A radially extending flat washer, seated within the interior wall, prevents axial movement of the expansion wedges in one direction. Thus, upon rotation of the threaded member, the central core will move axially toward the washer, forcing the second clamping surface to move only radially outwardly toward the first clamping surface. As such, because the flat washer restricts axial movement of the expansion wedges, relative motion between first and second clamping surfaces; i.e., between the collective wedges and interior wall, is limited to radial movement, only.
