The NPSM (National Pipe Straight Mechanical) thread is a straight pipe thread used in mechanical and low-pressure applications. It follows the ANSI/ASME B1.20.1 standard and features a straight thread profile with a 60-degree thread angle. Unlike tapered threads, NPSM threads do not provide a seal on their own and typically require a sealing mechanism, such as an O-ring or gasket, to ensure leak-proof connections.
