BSPP
Identification: The British Standard Pipe Parallel would be similar to the NPSM fitting. BSP threads are also known as Whitworth threads.
Seal: The BSPP male will connect with the BSPP female or female port. Both male and female have a straight thread and 30º seat and chamfer. The seal takes place by compression of the 30º seat on the chamfer. The threads hold the connection mechanically.
Comments: The BSPP fitting, although similar to the NPSM fitting, is not interchangeable. The thread pitch is different in most cases and the thread angle is 55º for the BSPP, as opposed to the 60º found on NPSM threads.
