    Default how tight to tighten a 1in union

    How tight should a 1in copper union be tightened?
    I have 2 that I have tried to tighten to no avail.
    Still very small leak under air pressure test of 40psi.
    I did sweat a threaded adapter to the union.
    The seal looks clean but dis-colored.
    Is there a way to lap the two matting surface's together?
