    use one of the fittings that you are using for the project at hand. I like to hand tighten the fitting on the thread and then back it off getting 3 to 3 1/2 turns. Adjust dies accordingly. The china fittings are horrible for tolerances, just have to live with some of the results.

      A pitch gauge is only going to tell you how many threads per inch, not if the dies are set to the correct depth. For that you will need a ring gauge.
