Recertify your bottles

If you change gassses, the bottle has to be repainted (of course)

--My supplier at Air Liquide (before they were bought) indicated that something changes in the valve on Argon vs Oxygen, but I never learned what, or if he was BS'ng me.

Is it possible there is some sort of flame arresting apparatus in the valve if its oxygen versus an inert gas?

My best guess is the valve seat material. In an oxygen environment, some seats are more dangerous. In the case of Noble gasses, that's not a consideration.

-just my best guess

The Oxygen valves will have a different thread size on the valve outlet and the valve itself is manufactured with some different components - typically viton o-rings, all lubrication will be oxygen safe like Christo-Lube MCG111 and the parts will be all Oxygen safe cleaned so no grease is present. Also I believe the oxygen valves are able to be back seated to prevent stem leakage- at least that was shop practice: acetylene just open enough for flow and the O2 was always wide open and back seated to prevent leaks. The bottles have to be O2 cleaned as well after hydro/inspection before any use with O2.
