Difference between NPT & BSP
NPT (National Pipe Thread) generally refers to tapered threads with 60°angles. It is an American standard thread.
BSP Union (British Standard Pipe) has 55°thread angles, the threads can be tapered (BSPT) or parallel (BSPT). Those threads are prevalent in Australia and the commonwealth countries.
Their thread pitch is different so that they cannot use together.
