Is there any good reason not to use a O2 regulator on a CO2 cylinder ? I live is South Africa and CO2 regulators are +- $150 where as I can get O2 regulators for +- $60
As I understand it O2 is at higher pressure, and more corrosive than CO2 and as such the regulator should be fine ? The only reasoning I can see not to use a O2 regulator is that the CO2 cools quite rapidly if the regulator is opened fully and that might cause a problem if the regulator gets to cold.
Any one that is more knowledgeable know why I shouldn't
