Conduit, pipe, and tube reamers that latch into screwdrivers to ream and smooth thin-wall conduit are among the plumbing hand tools and equipment. Flaring and swaging equipment are used to join copper tubing and gas pipes. Pipe extractors can be used to remove pipe, plugs, and fittings with broken threaded ends. Pipe supports and vises keep pipes in place so they can be welded and assembled. Pipe and tube brushes clean copper pipe inside and out in preparation for soldering or brazing, while tracing dyes help color code piping and septic tank systems and locate leakage.
