CO2Art CO₂ Resistant Tubing is a high-quality polyurethane airline designed specifically for pressurised aquarium CO₂ systems. With its strong pressure resistance and flexible construction, it provides a reliable connection between your regulator, bubble counter, check valve and diffuser while helping minimise unwanted CO₂ loss.
The clear 4/6mm tubing keeps your setup looking neat and discreet, making it a great choice for planted aquariums and aquascapes where you want the equipment to stay as unobtrusive as possible.

Installation Tip
When connecting the tubing to delicate glass CO₂ equipment:
✔ Dip the end of the tubing in boiling water for approximately 4 seconds to soften it
✔ Wet the glass connection before gently pushing the tubing into place
✔ If the tubing is still too tight, remove it and warm the end again before retrying
✔ Avoid forcing the tubing onto glassware, as this may damage the glass
