A 3/8 NPT fitting refers to a plumbing component that has a 3/8-inch nominal pipe size with National Pipe Taper (NPT) threads. NPT threads are a U.S. standard for tapered threads used to create a seal by wedging the threads together, which is common in fluid and gas applications to ensure a tight, leak-proof connection. The taper angle and thread profile are designed to improve sealing as the fitting is tightened.
