Two common pipe thread sizes exist, the tapered National Pipe Thread (NPT) and the straight National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM). The tapered threads are for joining and sealing, the straight threads are only for joining. Dry-seal thread (NPTF) allows for joining without sealants.

Commonly used sizes are 1/ 8 , 1/4 , 3/ 8 , 1/2 , 3/4 , 1, 1 1/ 4 , 1 1/2 , and 2 inch, appearing on pipes and fittings by most U.S. suppliers. Sizes smaller than 1 8 inch are occasionally used for compressed air, while sizes larger than 2 inches are uncommon, due to the use of alternative methods of joining that are used with these larger sizes.

Nov 13, 2020 · A semi-compatible variant of NPT is NPTF (National Pipe Taper Fuel). It ensures an even more leak-free seal. But it is important to note that using these variants together diminishes their leak-free characteristics. NPT threads should be burr-free and lubricated using lubricating paste or tape.

Apr 13, 2020 · 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 (34 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.
