Understanding 1 1/2 NPT Plug

When I first encountered the term “1 1/2 NPT plug,” I quickly learned that NPT stands for National Pipe Thread. This type of plug is essential for sealing threaded pipe ends in various plumbing and industrial applications. Knowing that the size designation (1 1/2 inches) refers to the nominal diameter of the pipe helped me understand how it would fit into my project.
