Wait a minute --
Why is it apparent that he was doing what you said he was doing?
Alhough I don't allways use O2 clean equipment, I'd say that you are 
foolish not to change the external O ring - it's right there in front of you.

You seem to be missing the point that IF the O ring had been secure, 
silicone or not, and if he  had been ussing a mixing valve this might 
not have occured. The other fact is that if Michael Jordan teaches you 
basketball you will probably never be as good as he is AND the fact that 
Sheck was his instructor doesn't mean he learned what was taught.
