I just got a propane smoker Dyna-Glo DGY784BDP 36" Vertical LP Gas Smoker. I have used it a few times and its great. The line that goes to the tank is super short and i want to extend the line. It is hard connected on both sides. I had ordered a 10' extension line when i got it thinking that i would be able add to the units line and just make it longer. I have looked around and every one says to use welding hose repair kit. I was wondering if anyone had used shark bite union compression connections for this. A copper barb union to cut and connect the lines together and then the copper crush ring to clamp/seal the lines to the union. Has anyone done this?
