Abstract

A manually operable tube flaring tool for providing a partial flare in the end of a deformable tube. The tool includes a flaring head defining an annular flaring surface and a cylindrical pilot portion projecting axially from the flaring surface to be received in the tube end for guiding the flaring surface axially against the distal end of the tube during the flaring operation. The tool further includes a support for fixedly positioning the tube end coaxially adjacent the flaring surface of the flaring head. The support defines an improved recess configuration providing a controlled buckling of the tube end by the forceful engagement therewith of the flaring surface wherein the buckled tube end defines preselected frustoconical inner and outer portions. The support may further define a conventional single flare recess opposite the partial flare recess whereby the tube may be used selectively to provide either of the partial or single flare flaring operations. The tube clamp may be defined by one leg of the U-shaped body and a cooperating clamp block movably carried by the body and adjustably positioned by a threaded member threaded through the other leg of the body.
