Abstract:

A tapping tool for repairing damaged threads on PVC pipe and PVC pipe fittings (e. g. T-connectors, elbows, etc. ) includes an elongate shaft with a handle member fixed to a proximal end and a head fixed to an opposite distal end. A threaded tap formed of hardened steel is positioned and disposed on the head for forced, threaded engagement with the threads of the PVC pipe or fitting. Manual rotation of the handle serves to advance and withdraw the head along the threads of the PVC pipe or fitting as the tap cuts and reshapes damaged threads, thereby restoring the threads of the PVC pipe or fitting to a uniform, functional condition.
