Measure National Pipe Taper Threads

Measure pipe threads
This feature only available for Windows PCs and tablets.

Use this application to easily calculate the values required to measure Amarican National Pipe Taper threads when there is no gauge available.

Pitch diameter micrometers are best to use for this purpose, but we have included 3-wire measuring values in the calculations.

The NPT thread measuring calculator will supply the pitch diameter at any point along the length of the thread.
The number of turns of a thread guage is also shown.
