The pitch of the threads (i.e. distance between each thread) are the same (14 threads per inch) The main differences are subtle and reside in the profile of the threads. The profiles have 2 main differences (NPT vs. BSPT): The angle of the profile of the thread (60-deg vs. 55-deg) Tips of the profile of the thread (flat vs. round)

NPT threads differ from BSP threads in the tooth angle, which is 60 degrees instead of 55, and the edges are more pronounced. Another difference is in the pitch: NPT threads have 11.5 threads per inch while BSP threads have 11 threads per inch. NPT threads are tapered in both and male, although there are variants that we will explain below.

The angle across the flanks of threads is 55 degrees instead of 60 degrees as it is for NPT. On a BSPT tapered thread there are no shoulders to seal with a washer. The reason being that the thread designs are different, NPT is a sharp thread and BSP is a rounded thread. ISO threads have 55 o taper angle versus 60 o for NPT.

R/Rc Thread Connection Conical Pipe Thread Connection According to ISO 7/1 (other common descriptions are BSPT, Kr) Male: ie. R 1/4" : ie. Rp 1/4" (parallel) NPT Thread Connection National Pipe Thread American Standard According to ANSI/ASME B 1.20.1 Male: ie. 1/4" NPT : ie. 1/4" NPT: Male Thread 1/8" NPT 1/4" NPT 3/8" NPT

A semi-compatible variant of NPT is NPTF (National Pipe Taper Fuel). It ensures an even more leak-free seal. But it is important to note that using these variants together diminishes their leak-free characteristics. NPT threads should be burr-free and lubricated using lubricating paste or tape.

BSP vs BSPT. The difference between British Standard Pipe (BSP) and British Standard Pipe Taper (BSPT) is that BSP threads are parallel while BSPT threads are tapered. The thread angle, pitch and shape is however the same. Again, it means that telling BSPT and NPT threads apart will also not be easy unless you keenly check the thread angle or

e.g. for R & Rc ½" the distance is 8.2mm, 1" is 10.4mm and 2" is 15.9mm. for NPT ½" the distance is 8.13mm, 1" is 10.16mm and 2" is 11.07mm. N.B. The diameter given for a pipe thread refers almost always to the hole diameter and not the pipe outside diameter. Taper threads normally have a much larger pitch diameter tolerance than

NH = NST. Fire hoses with National Pipe Straight Hose Thread (NPSH) has the same threads per inch as National Pipe Thread (NPT) but the threads do not taper. This allows a coupling to thread onto a NPT fitting without being a permanent connection. Both NH / NST and NPSH are "straight" threads which means the threads are consistent

Both threads have the same pitch and the familiar shaped peaks and valleys. However, the designs of the threads differ in two fundamental ways. With NPT, the peaks and valleys of the threads are flat. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees. NPT
