National Standard Taper Pipe Threads Size NPT Chart
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
Straight Pipe Threads Table Chart ANSI – WESTport

How to Measure a Taper Pipe Thread & Choose the Right Gauge
Understanding Taper Pipe Threads The National Pipe Taper (NPT) Standard At the core of taper pipe threads is the National Pipe Taper (NPT) standard, governed by the ANSI/ASME B1.20.1 specification. NPT threads are known for their taper ratio—1 in 16—meaning that for every inch of length, the diameter decreases by 1/16 inch.
