NPT (National Pipe Taper) and NPSM (National Pipe Straight Mechanical) are both American standard pipe thread types, but they differ in their threading style. NPT threads are tapered, meaning they become narrower as they extend, creating a tighter seal as they are tightened, which is ideal for sealing pipes. In contrast, NPSM threads are straight and do not taper, requiring a gasket or O-ring to ensure a proper seal, often used in mechanical and low-pressure applications where a tight seal isn't critical.
