Why are there both NPT and BSPT threads?
NPT threads are commonly used in the United States.  BSPT are widely used in other countries.

Q. Does ATP offer fittings in BSPT, BSPP, NPT and NPS?
We offer almost all of our fittings in multiple available thread patterns. Please look at our Fittings Catalog or Contact us if you wish to confirm availability.

Q. Can NPT or NPS be fitted to BSPT?
Never try to mate a BSP fitting with an NPT or NPS fitting if the pressure holding capability is at all critical.

Q. Are NPT/NPS threads compatible with BSPT?
No, the thread forms are different and most have a different pitch. 

Q. How are the thread pitches different?
NPT/NPS threads have a 60° included angle and have flattened peaks and valleys ; BSPT threads have a 55° included angle and have rounded peaks and valleys.

Q. How do I determine the pitch?
Use a thread gauge or count the number of threads that fall into a 1" span..
