A3/4” NPT pipe thread has an outside diameter -OD - of 1.050 inches. Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4” NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI. 1)

Whileexternal and internal tapered pipe threads for joints can be used for all purposes, there are also mechanical joints where parallel threads work better. They are used in pipes of iron, steel and brass where there is no internal pressure. ( N ational P ipe S traight M echanical), formerly known as NPS. The flank angle is 60°, the profile
