Regular airline tubing is not suitable for CO2, it gets crusty and turns into mush. Avoid at all cost.

Silicone is thought of as an acceptable alternative. Although it will not get crusty, but it does loose 6% of CO2 for every foot, so if you have 5 feet of silicone tubing, your loss rate is 30%.

The best and most efficent CO2 tubing is polyurethane. Clippard manufactures this tubing, it is the first one on this link. Simply select the size (regular aquarium use CO2 tubing is 1/4"OD and 1/8" ID)and color, find a dealer in your area and order it through them to avoid the shipping and handlinr charge.

Check out this CO2 tubing comparision chart and look at the permeability rates of CO2 vs. Polyurethane
