Remember, pipe threads are tapered and only go so far, they are not like bolt threads. Pipes tighten by the threads wedging the two tapers together. I think this is the main reason people break them off.
Turn 1/4 to 1/2 then turn back to break the curl stop when it gets tight.
You do what you have to do, so you can do what you want to do!
