ABSTRACT:
A tube expander for expanding or flaring the ends of automobile exhaust pipes and the like includes a segmented expander die having an arbor slidably received within the expander die segments for expanding the die upon movement of the arbor in a first predetermined direction. A manually operated device initially moves the arbor in the first direction to expand the die until the die segments engage the interior surface of the tube end to be expanded, and a separate independent hydraulic mechanism is then operated to move the arbor in the first direction in order to flare the tube to increase its diameter by a predetermined dimension. The compact structure provided enables the tool to be manually operated to flare tubes in situ on an automobile.
