Abstract
An improved tubing expansion apparatus is disclosed which greatly facilitates convenient expansion of tubing, such as for repair and replacement of motor vehicle exhaust systems. The apparatus includes a hand-holdable expander unit and a separate pressurized fluid supply unit joined in fluid communication with the expander unit by a flexible fluid conduit. In order to provide selective control of the fluid supply unit from the expander unit, a trigger-like electrical switch is provided on the expander unit to permit remote operation of the fluid supply unit. Other features of the apparatus enhance its versatility for conveniently effecting varying degrees of expansion on tubing of different dimensions.
