A high quality, machined, NPT, fitting will probably be about three quarters to one full turn from hand tight. After that you risk stretching threads and then the fitting is toast.
Mike, had no idea. I thought I had to use much more force to keep it from leaking. Can't tell you how many turns I used, I'm sure it was more than what you advised. I'll be much more aware in the future, if I need to redo any of those joints. That is exactly what I needed to know.
