Excellent product. See the attached picture of the fitting I bought to be able to use a regular gas hose with this regulator. It is manufactured by Western Enterprise and the part number is AW-405. It has a 9/16"-18 plug and a 5/8"-18 socket. The inert gas hose uses standard 5/8"-18 ends so it works perfectly. This adjustment in turn makes the regulator compatible with American products. If you don't have this fitting, all you have to do is use clamps. I just prefer a clean look. Hope this helps someone else as it took me a while to find this part!
