I have an aluminum gas bottle I don't need. It's completely empty but, can be refilled. According to the label on it, it can be refilled with various gas options, I don't make up the labels, I'm just the person selling it. Whoever wants to refill it, would have to abide by the manufacturer specs, and re-fill procedures. See the pictures for the gas options. It's an expired cylinder, 2009, which would need to be re-certified, and it's about $150. And if you are looking for an item, that's not listed, then I DON'T HAVE IT. But, you can still roll the dice and ask me. Specs of the bottle: 30AL DOT: 3AL SERVICE PRESSURE: 2,015 PSIG APPROXIMATE CAPACITY: 4 CU. M.
