I realize the OPD is a safety device, but it seems it should not be depended on to be a shutoff instead of closing the valve. It's along the lines of don't depend on the OPD to stop the flow when filling the cylinders. The vendor is a rather large welding supply provider in the Phoenix metro area. They have a number of stores, but only one shop that certifies and refills the portable cylinders. They keep a few of each size in stock at the stores for retail sales. My options when I needed filled tanks were kinda slim. Drive 20 miles to drop them off, then go back in a couple days to pick them up. These guys were close and had them ready for a very reasonable price. And I already had purchased 2 new ones, and didn't want to repeat that.
