CO2 Resistant Tubing 5m

Standard airline tubing is highly permeable to CO2, causing significant gas loss before it reaches the diffuser and resulting in inconsistent bubble counts and poor efficiency. This CO2 Resistant Tubing is manufactured from a specialised silicone compound with greatly reduced CO2 permeation, ensuring the gas you pay for actually enters the aquarium. The 4/6mm inner/outer diameter is the universal standard for aquarium CO2 systems and fits all bubble counters, check valves, solenoid barbs, and diffuser inlets without adapters. The 5-metre coil provides sufficient length to route tubing neatly through the aquarium cabinet from cylinder to tank without joins. The tubing remains flexible at room temperature for easy installation and is compatible with all standard push-fit and barb CO2 fittings.
