CO2-Proof Tubing - Normal airline tubing can lose up to 20% of CO2 through its membrane. Silicone tubing reacts w/ CO2 and render it less efficient (thus the silicone hardening over time under CO2 usage). Our special CO2 Resistant Tubing loses less than 1% of CO2. Also perfect for saltwater use (eg: Kalkreaktor). Rated Class I for both CO2 and saltwater applications. Unlike other so-called CO2 Tubing which is rigid, ours is soft and flexible. Choose between transparent green, transparent blue and black. 4/6mm -ID/OD.
