A 3/4 NPSM refers to a National Pipe Straight Mechanical (NPSM) thread size. This is a type of straight thread used in mechanical joints where a seal is achieved with a gasket or O-ring rather than the threads themselves. The nominal size of 3/4 inch indicates the approximate inside diameter of the pipe, while the thread pitch and dimensions conform to specific standards for NPSM threads.
