Standard Plumbing Tapered Pipe Taps

pipe tap
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.

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.
