While all of the above may be true, allow me to say that I have been using 
a used 2-stage O2 regulator on CO2 tanks since 1990. That's over 15 years, 
and it continues to work just fine. The female fitting that came with the 
O2 regulator had to be changed, because CO2 tanks have a larger diameter 
male threaded connection.
