Every CO2 supplier we could find in the Oklahoma City area (Oklahoma) was checked one by one, and 10 of them made the list. 1 will refill the cylinder you walk in with. 1 only swap it for a different tank, which matters if yours is new or an odd size. 8 would not confirm either way, so those are marked call to confirm rather than guessed at. 2 confirm food grade CO2 for anything you actually drink; the common sizes here are 10lb, 15lb, 2.5lb; most cover industrial, welding, soda.
