Standard Plumbing Tapered Pipe Taps

A plumber's toolbox isn't complete without a full set of pipe taps. Adding a tapered thread to the inside of an existing pipe or tube will help it seal better, and PlumbingSupply.com® has the pipe taps you need. Don't get caught without the right tools for the job! These are NPT pipe taps used to create threads or to rethread metal piping and fittings, or other metal fabricated objects. Threads properly shaped will provide a tight seal for piping used in the transfer of liquids and gases. These taps can be used with aluminum, brass, copper or steel.

Pro Tip: When using a pipe tap, turning the pipe tap slowly forward (clockwise) half a turn and then slowly back (counterclockwise) half a turn will help to rid any metal chips or slivers created by the tap cutting into the metal. This process will help keep your threads clean as you continue to tap new threads.
