Abstract
A tubing bender device includes a frame, handle, ratchet mechanism, slide rod and a frame notch. The tubing bender may be easily disassembled and assembled into a forward or reverse configuration through the use of connectors, two brackets and a bending mandrel. Reversibility is also provided by a cross bow bar support releasably secured to either the slide rod or to a bracket. The cross bow bar support may also be inverted to position die heads in either an upward or downward direction. Repositionable die heads may also be rotated relative to the support into an operative configuration when bending smaller diameter tubing. The repositionable die heads are rotated relative to the support into a non-operative configuration when bending larger diameter tubing.
