http://www.apollointernational.in/iso-metric-thread-chart.php WebA 3/4" 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.
