    functional fitting by Henry - Ortonville, MichiganApril 12, 2012
    the tolerance between the nut and the fitting threads is sloppy and any amount of torque causes the nut to slip on the threads. a good beading of sealant is what will really hold this in place. but then this is for above the waterline and you get what you pay for. bottom line, it works.
