WebNPT fittings are slightly tapered so the “nominal” diameter is the diameter in the middle of … NPT is defined by ANSI/ASME standard B1.20.1. The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3⁄4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread. The half-angle (between the taper surface and the axis of the pipe) is arctan(1⁄32) ≈ 1.7899° ≈ 1° 47′.
