A 3/8 NPT thread refers to a National Pipe Taper (NPT) thread size, commonly used for pipes and fittings in North America. The "3/8" denotes the nominal pipe size, which corresponds to an outer diameter of approximately 0.675 inches, although the thread dimensions and pitch are standardized to ensure a tapered, sealing fit for fluid or gas connections. NPT threads are designed to provide a tight seal, typically requiring the use of thread sealant or tape.
