very nice fitting……its nice to have a union with flats on it for wrenches instead of tearing it up with pliers……well worth the cost

I purchased the 3/16-40 UST Union and this thing is a marvel. Well worth the price, particularly as I used it not only to bridge the Boiler to the Engine……but as a quick disconnet for tearing down my boiler…….(hybrid – Jensen #85 Boiler mated to a firebox and propane/butane burner of my own design).
Not that bad
