BSPT (British Standard Pipe Thread) is similar to NPT except for one important difference. The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT. Thus an NPT male will fit into a BSPT fitting or vice versa but they will not seal. This is a popular fitting in China and Japan but is very rarely used in North America unless the equipment to which it is attached was imported. Thread sealant is needed to seal the male and female fitting together. Ralston Instruments has adapters to both male BSPT adapters and female BSPT adapters.

The difference between BSP and NPT is the size of the angle between the flanks of threads (from root to crest and back to crest). This angle is 55 degrees for BSP and 60 degrees for NPT. This means that an NPT male fits into a BSPT fitting and a BSPT male will fit into NPT fitting but they do not seal. See the link below:
