Fzone Co2 Proof Tubing

Fzone CO2 Proof Tubing allows a leak-free function ensuring no carbon dioxide will escape. Regular airline tubing can cause a 20% loss of CO2 & will not fit snug on the diffuser. CO2 tubing can also fit on standard airline fittings. We advise you to attach a CO2 check valve to the tubing ensuring no backflow to the CO2 regulator. CO2 airline tubing can degrade over time, so it should be replaced once every 3 years. CO2 Tubing is a commonly overlooked essential for your CO2 set up.
