(mm) Pressure Ratings, psig (bar) A E NPT- National Pipe Thread - is the US standard. Most of the rest of the world uses BSP - British Standard Pipe. NPT has flattened peaks and troughs where BSP is rounded. NPT has a thread angle of 60º where BSP is 55º. At certain sizes, NPT and BSP share the same number of threads per inch - at ½" and ¾" - but at all other sizes the two are AN/ NPT / Metric / INCH (SAE) Conversion Charts. "AN" Thread Sizes (Army/Navy Threads) Commonly used on Nitrous Oxide systems. The sizing chart and numbering system was developed during World War II where the armed forces used Nitrous Oxide systems to boost the power output of aircraft engines.
