Abstract: Disclosed is a hand tool for wrapping sealing tape such as unsintered polytetrafluoroethylene around the end region of threads on a cylindrical conduit or pipe. The tool includes a holder for a tape dispenser which has mounted thereon a tape cutter so that the dispenser with a roll of tape rotatably held therein is a complete unit usable independently of the tool. The dispenser has a flange, however, which is slid into a groove in the tool and held frictionally therein by a leaf spring in only one predetermined position so that the free end of the tape is presented between a grooved roller and the threads of the pipe. A third roller, mounted on the end of a hand operated lever, is spring-pressed against the opposite side of the pipe wall so that the grooved roller is pressed against the tape to force the tape into the threads, the tool being rotatable about the pipe to wrap one or more turns of tape around the pipe threads. The grooved roller is one of three rollers each having a different number of grooves per inch to adapt the tool for use with pipe threads having a range of pitches, the three rollers being mounted on a turret so that the appropriate roller can be selected and made effective for a given thread within the designed range of pitches.
