I believe the last question may have answered my query, but just a little clarification would be great! I get "Blue Rhino" propane gas grill tanks as pictured that have horrible huge proprietary outside male threads, not fitting anything other than the grill hose attachments really. I have a spare gas (not O2) dial regulator and it's not even close to fitting! Not long ago they changed all the grill tanks too for safety reasons and the threads are way different. It doesn't look like the turbo torch regulator will thread onto a new style gas grill tank does it? I'm sure a welding supply store has industrial propane tanks that will fit appropriately, but Id prefer to use the swap it out Blue Rhino tanks you see everywhere if possible. I'm not interested in the smaller camping type of propane tanks but the standard modern new propane tanks. thanks a lot.
