I think ro/di tubing (rigid airline tubing) is polyethylene as opposed to polytetrafluoroethylene.

thanks, been looking up information on tubing types for CO2 and I found out what the rodi tubing is. Its polypropylene and it has a CO2 diffusion rate of 90, compared to polyethylene at 280 and vinyl at 360. Polyethylene is what all the online stores are selling as CO2 resistant tubing. Its really barely any less than regular airline tubing.

Tubing we use on our RODI systems is LLDPE (linear low density polyethylene)
