ABSTRACT OF THE DISCLOSURE In a device for confining a pressurized working fluid within a tube to be expanded radially, a support to be positioned axially within the tube and at least one sealing member encircling the support. The sealing member is deformable so that it expands radially against the inside of the tube upon axial compression by the force of a pressurized working fluid introduced into the tube. A centering means is provided that prevents angular movement of the sealing member relative to the longitudinal axis of the tube, thereby forcing the sealing member to assume a radially centered position within the tube as it expands.
