M&P carries NPT tapered plugs to protect internal pipe threads. These plugs will protect your product during shipping and storage until needed for use. NPT Plugs are generally in stock. The NPT tapered Plug is designed to push into the inside of NPT pipe for protection.

NPT TAPERED PLUGS DESCRIPTION

  • Used to protect NPT threads on the inside.
  • Push-in Design.
  • Made from Polyethylene.
  • Colors vary; most sizes are RED in color.


National Pipe Thread Taper
(NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. In contrast to straight threads that are found on a bolt, a taper thread will pull tight and therefore make a fluid-tight seal. NPT is defined by ANSI/ASME standard B1.20.1. Pipe threads are different from machine-screw and bolt threads. The biggest difference is the taper on pipe threads. Nominal Pipe Size (NPS) is loosely related to the inside diameter of Schedule 40 pipe.

See Size Chart for the sizes of NPT tapered plugs available.

We also have NPT Threaded Plugs to protect the inner diameter of NPT Pipe.
