Do you know the proper number of internal and external MPT threads to cut into pipe and fittings, so they make up properly?
You want hard copper for threading as well. As far as number of threads, Ive found its just trial and error. Run the die over the pipe till the end of the pipe is flush with the back of the die. Then start with the tap and play with the depth till you get a fit you like. I have American Model Engineering Supply taps and dies and have found I need to leave about 2 threads of the tap sticking out of the hole.
