Basic Dimensions, American National Standard Taper Pipe Threads, NPT, (ANSI B2. 1-1968)
| Nominal Pipe Size | Outside Diameter of Pipe | Pitch of Thread |
|---|---|---|
| 1/16 | 0.313 | 0.03704 |
| 1/8 | 0.405 | 0.03704 |
| 1/4 | 0.540 | 0.05556 |

What does 1/8 NPT stand for?
A 1” NPT MALE CONNECTION HAS AN OUTSIDE DIAMETER (OD) OF ABOUT 1.3”. AN 8” PIPE HAS AN OD OF ABOUT 8.6”. THE MEASUREMENTS ARE “TRADE SIZES.” THAT MEANS THEY ARE UNIFORM SIZES ACCORDING TO THE DIAMETER OF THE PIPE OR FITTING THAT THEY CAN BE USED WITH.
What is a 1/8 thread size?
NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1″ span….BSP vs NPT.
| Trade Size | Pitch (Threads per Inch) | |
|---|---|---|
| 1/8 | 27 | 28 |
| 1/4 | 18 | 19 |
| 3/8 | 18 | 19 |
| 1/2 | 14 | 14 |
What is the pitch of NPT?
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°).

What is thread pitch?
The thread pitch is the distance between corresponding points on adjacent threads. Measurements must be taken parallel to the thread axis. • The major diameter or outside diameter is the diameter over the crests of the thread, measured at right angles to the thread axis.
