NPSM stands for National Pipe Straight Mechanical, which refers to a type of thread used in mechanical pipe connections. Unlike tapered threads, NPSM threads are straight and are typically used in applications where a seal is achieved with a gasket or O-ring rather than thread interference. These threads are commonly used in plumbing and industrial applications to ensure a leak-proof connection without relying on the threads themselves to create a seal.
