WebOct 19, 2011 · National Pipe Thread Tapered Thread ( NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. The taper rate for all NPT threads is 1⁄16 ( 3⁄4 inch per foot) measured by the change of diameter (of the pipe thread) over distance. The angle between the taper and the center axis of the pipe is 1° 47′ 24″ (1.7899°). WebJan 1, 2024 · The taper for American Nations Standard Pipe Tread is: 1 in 16 or 0.75" per foot.
