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.
