I recall seeing a table of tubing materials that listed CO2 transmission rates sometime ago. I'll see if I can locate it. I vaguely recall PVC tubing being one of the better options.

Well, here's one. Wasn't the original one I saw before but should be good enough for you:

And as a bonus it lists ozone resistance as well...just saw that!
