National Standard Taper Pipe Threads Size NPT Chart - Includes both External and internal Pipe Thread Data. 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°).

Minimum = 0.033P for all pitches. See table for maximum. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, …
