However, i keep having trouble figuring out what kind of threads go with what.. NPT, NPTF, BSPT, I seem to go in circles and get confused.

Anybody out there good with pipe threads?

Tanks usually (99.9%) come with NPT threads so NPT or NPTF fittings will work with them. FYI NPT & NPTF threads are interchangeable with use of PTFE tape.



Finding fittings that use BSPT threads in the US might be a problem.

Finally my apprenticeship years as a pipe fitter/ boiler operator come in handy here
