NPSM stands for National Pipe Straight Mechanical. It is a type of pipe thread that is straight, not tapered, and is used primarily for mechanical joints where a seal is achieved through the use of a gasket or an O-ring, rather than through the thread itself. NPSM threads are commonly used in applications where a leak-proof seal is not required from the threads alone.
