Brubaker Tool's 3/4-14 NPT taps are high-speed steel taps designed to cut 3/4-inch National Pipe Taper threads at 14 threads per inch. In Brubaker's 2016 catalog, this size is offered with five flutes and is available in both NPT and NPTF variants—13105-23-B for NPT and 13305-23-B for NPTF—each built on a standard high-speed steel substrate. These taps are intended for general-purpose threading in metalwork, enabling the production of pipe-threaded holes that meet common ANSI standards for 3/4-14 NPT or NPTF connections.
