Certainly! The primary difference between 1/2 NPT (National Pipe Taper) and 1/2 NPSM (National Pipe Straight Mechanical) is in their thread design. NPT threads are tapered, meaning the diameter decreases along the length of the threads to create a tighter seal as they are tightened, often requiring a sealant. In contrast, NPSM threads are straight and do not taper, relying on a gasket or O-ring for sealing rather than the threads themselves.
