I had to put the unit back together so dinner could be cooked yesterday with the 1 lb. tank, but the products I bought are identical to these two images in the posting. Again, my problem is I am unable to attach the "Anderson Metals - 54048-0602 Brass Tube Fitting, Half-Union, 3/8" Flare X 1/8" Male Pipe" which was listed in your original posting, to the Gas Valve (see photo Gas Valve) The threads don't match. The new Fitting did fit the examples to prove it was1/8" threads at the Hardware Store. The problem for me is the gas valve (see photo Gas Valve) will not attach because it is not 1/8", it will not screw into the samples that the Hardware Store uses to verify thread count. This problem is the same problem That you always get when attempting to attach US threads to Metric threads.
