Thanks for the correction.  "Silicon" is the name for the tetravalent
nonmetallic element (you'll find it number 14 with a bullet on your
periodic table), while "silicone" is generally used to refer to
polymeric compounds containing the element and lsightly less often to
any material that contains any amount of such oymeric compounds.  The
difference is not lost on me.  I mad a mistak.  ;-)

Adding your findings to the mix, it seems that any normal vinyl AND
rubbery-flubbery tubing will do just fine for CO2 injection and no
special tubing is necessary.  The tubing just has to fit the parts. 
Therefore, beware of those that tell you that you need or try to sell
you "special" CO2 tubing.
