NOTE: It is a common mistake to identify a BSPT (tapered) as an NPT. Remember that NPT threads have a 60° thread flank angle, and BSPT has a 55° angle (this can be verified with a thread gauge). Although BSP is a foreign thread, it isn't metric. This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. Thread conforms to ISO 228-1.

1) Measure the O.D (Outer diameter) of the BSP thread. 2) Take the O.D measurement in inches and subtract 1/4 (.25″). For example, a BSP 

The main difference between NPT and BSP threads is that the thread angle in NPT threads is 60 degrees while that of BSP pipes is 55 degrees. NPT threads are also pointed at the crests and

You can cross-reference the bore size on the following chart with thread pitch and threads per inch to find your desired size and its related specs. BSPT-tech.

BSP Thread Type - British Standard Pipe You'll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don't get confused, the actual measurement is not the same as the NPT pipe size. Is SAE and UNF the same?

04/10/  · The second kind of BSP thread is the taper thread. The British Standard Pipe Taper thread (BSPT) has a changing diameter. It may increase or decrease along the length of the thread. Some taper threads have the letter R on them as an identifier. It's common to incorrectly identify tapered pipes as NPT pipes. However, NPT pipes have a 60° flank
