Taper pipe threads I have found are fairly standard world wide on the
inch system. I do know however that the BSP (British Straight Pipe) ,
at least on the 1/8 inch size differers in threads per inch. 1/8 NPT
has 27 threads per inch where as the 1/8 BSP has 28. I have taps and
dies for both in my collection.
