I have sold many many reels of rubbery-flubbery silicone tubing (silicon 
tubing would likely be made of glass) and it has shown no signs of breaking 
down in three years.  Any plastic or glass tubing should resist degradation 
by CO2 very well.   The most important thing about the tubing is that it 
makes a good seal with the fittings used and stays on.
