NPT = symbol for the thread series and form (i.e., National (American)Standard Pipe, Taper) Basic dimensions are given to four or five decimal places to eliminate errors when calculating gauge dimensions, they do not imply a greater degree of precision than is normally obtainable.
3/8-18 NPT : Pipe and Fitting Thread Dimensions and Tolerances. All the relevant data for this tread in one spot.
3/8-18 NPT : Basic Thread Dimensions (Pitch, minor & major diameters, depth, lead), Tolerance range for all applicable classes and much more.
NPT Thread Chart for basic dimensions of general purpose NPT pipe threads (inch) according to ANSI/ASME B1.20.1 standard.
NPT consists of both internal and external taper threads that are intended to be wrenched with a sealant to create a pressure-tight joint. These threads have a taper of 1 inch per 16 inches of length— meaning that the diameter measured diametrically relative to the axis decreases by 1/16 inch for every inch of length.
The Jargon, calculations, and charts that define NPT threads are very different compared with standard metric and inch threads. This webpage will explain the difference between the various series, how each parameter is defined, and show how to find the correct basic dimensions and tolerances for each thread.
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.
