NPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to as MPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT(F) for female interal threads. A thread sealant must always be used to achieve a leak free seal (except for NPTF). It is also based on Trade Size rather than actual diameter (similar to BSP in this regard).
Both threads have the same pitch, angle (60 degrees) and shape (flat peaks and valleys).
The below table gives the Threads Per Inch, Pitch and Major Diameter for NPT Threads.
NPT threads are common in the United States and also used in Australia, BSP threads are widely used in many other countries.
BSPT -British Standard Pipe Taper
BSPP -British Standard Pipe Parallel
NPT -National Pipe Taper
NPS -National Pipe Straight
While the actual specified outside diameters of American National Pipe differ slightly from those of British Standard Pipe, either thread may reliably be cut onto a pipe of its respective trade size. BSPT equivalent is NPT and BSPP's equivalent is NPS.
