NPSM stands for National Pipe Straight Mechanical, which refers to a type of pipe thread used in mechanical applications. Unlike tapered threads, NPSM threads are straight and do not provide a seal on their own; they are typically used in situations where a seal is achieved through other means, such as an O-ring or gasket. These threads are standardized by ANSI/ASME B1.20.1 and are commonly used for mechanical connections where pressure-tight sealing is not required.
