CO2 Resistant Aquarium Polyurethane Tubing - 4/6mm
Premium quality CO2 resistant tubing for planted aquariums. High pressure rated. Great for use with our CO2 accessories and complete kits!
This tubing is very different to all other types of on the market in terms of what it is made of - other brands do not use the right type and as a result, the tubing becomes brittle and leaks gas. This tubing will last indefinitely.
Fits all CO2 glass diffusers from our shop.
 
Tip: To attach tubing to CO2 glassware, dip the end of the tubing in boiling water for 2 seconds, then simply push onto the glassware.
