Abstract
An apparatus and process for selectively expanding the wall of a tube by compression and subsequent radial expansion of one or more elastomeric bars lodged within longitudinal slots of a bushing positioned inside the tube. Expansion of the elastomeric bars against the inner surface of the tube results in expansion of the tube wall at intermittent locations about the circumference of the tube.
