Pipe Thread Size National Pipe Threads (NPT) Pipe sizes do refer to
physical dimensions, but the plumbing industry standard for the sizes of
pipe is not always as straight-forward as measuring the pipe. Measuring
the pipe will oftentimes mislead you into choosing the wrong pipe, so
do take care. The "pipe thread size" as shown in column 3 of the table
below is measured and based on the inside of the pipe. But, to actually
determine the size of a pipe, the outside diameter of each pipe or
fitting must be measured and compared to the table for size
identification. For example, a 3/4" NPT pipe thread has an outside
diameter of 1.050 inches. Each thread size has a defined number of
threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per
inch. Both the TPI (threads per inch) and OD (outside diameter) of the
thread are required for positive identification of thread size because
several sizes have the same TPI.
