Review on Allstar Performance ALL50185 Female Union by Travis Carter

These are simply brass fittings. The thread is cut deep enough, the brass is not too thin. (I break all thin ones because of tightening) The difference was Allstar Performance shipped them twice as fast as all the other parts I ordered at the same time. Why can't other sellers ship this quickly? Some other carriers took several days to put my parts in boxes so they don't get any feedback from me.
