CO2-Resistant Airline Tubing — 5m

This 5-metre roll of CO2-resistant silicone-blend tubing provides an ample length for aquarium setups where the CO2 cylinder and regulator are positioned at a greater distance from the tank, such as in a sump cabinet or on a separate stand. The CO2-resistant formulation prevents the permeation losses that plague standard airline tubing, which can account for a surprising proportion of wasted CO2 in a pressurised system. The 4mm inner diameter fits all standard CO2 equipment fittings. The extra length makes it easy to route neatly behind equipment and along aquarium cabinet trim without tension on fittings. Any unused length can be stored sealed for future use or cut to supply a second tank.
