Measure the inner diameter (ID) of the female thread and the outer diameter (OD) of the male thread. This number will help determine the thread dimension. After measuring the threads on a fitting, you must match the number to a thread chart to determine the nominal size. Thread size and pipe size are measured according to the same scale.
How can you tell the size of a pipe fitting?
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.
How can I tell if these pipes are gas lines or..?
Hold the pipe and have a helper turn a nearby tap on/off quickly, to see if you can feel vibrations. Try running the water for a bit, then touch the pipe to see if the temperature changes.
