NPT is defined by ANSI/ASME standard B1.20.1. [5] 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
= 0.75 in./ft . - The angle between the sides of the thread is 60 deg. - Thread Designation: The no
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″ (1.7899°)

They seal due to the out of roundness principle which means that the male stretches the female fitting until there is so much force that the connection can hold pressure NPT Thread Calculator for NPT thread dimensions according to ANSI/ASME B1.20.1 standard. - For left hand threads, include LH to the designation. (Example: 1/4 - 18 NPT - LH) - For pressure-tight joints, it is intended that taper pipe threads be made up wrench-tight with a sealant

Male NPT is denoted as either MPT or MNPT Female NPT is either FPT or FNPT Pipe thread sizes do not refer to any physical dimension. The outside diameter of each pipe fitting must be measured and compared to the table for size identi-fication.

NPT and BSP thread pitches (threads per inch, TPI) are listed below. 1 /2NPT to 1/2BSP. Both have 14 threads per inch so they match up quite well.The primary difference is in the pitch (angle of the thread) which is 60 to 55. Use a PTFE tape and they screw together and seal OK
