Abstract:
A tool for repairing damaged threads on PVC pipe and PVC pipe fittings comprising:an elongate shaft having a proximal end zone and an opposite distal end zone; a handle fixed on said proximal end zone; a head fixed on said distal end zone; said elongate shaft, said handle and said head being fixed in rigid non-moving position relative to one another as in integral, one-piece unit; said head including a thread tap defined by a cylindrical wall terminating at an annular rim and surrounding a hollow interior, and said cylindrical wall having an outer circumferential surface formed with threads for forced threaded engagement with the damaged threads of the PVC pipe and PVC pipe fittings and said thread tap on said head being structured and disposed to cut and reshape the damaged threads upon advancement and withdrawal of said head relative to the damaged threads by manually rotating the handle and thereby restoring the damaged threads to an operable condition; and said head further including a plurality of axial slots cut through said cylindrical wall, in communication with said hollow interior, and extending from said annular rim and towards said handle along at least a portion of a length of said head measured between said annular rim and said distal end zone of said shaft, said plurality of axial slots allowing yielding inward movement of said cylindrical wall towards said hollow interior in response to inwardly directed radial forces upon advancement of said thread tap of said head along the damaged threads of the PVC pipe and PVC pipe fittings.
