Abstract
A working element operable to expand an end of a tube includes a main body configured to rotate about an axis, a plurality of roller supports movably coupled to the main body, the roller supports movable relative to the main body between a retracted position and an expanded position, and a plurality of rollers coupled to the roller supports such that a distance between a first roller of the plurality of rollers and a second roller of the plurality of rollers increases when the roller supports move toward the expanded position. The rollers are configured to be inserted into the end of the tube when the roller supports are in the retracted position, and the rollers are engageable with an inner circumference of the tube when the main body rotates about the axis to expand the end of the tube.
