CO2 Resistant Aquarium Polyurethane Tubing- 4/6 mm
Choose a premium quality CO2 resistant tubing. Designed by CO2Art for safe connection of the CO2 equipment for your planted aquarium!

This excellent tubing stands out because of its high-quality Polyurethane and resistance to high pressure. Most brands do not use the suitable material and in consequence, the tubing becomes brittle and leaks CO2 art a short period of time.
With proper maintenance you can enjoy our tubes up to 30 years of use!

Tubes are available in 3 lengths and 5 colours:


  • 3.3 ft (1 meter)
  • 10ft (3 meter)
  • 20ft (6 meter)


  • Clear
  • Black
  • Silver
  • Green
  • Blue

All of our tubes are compatible with our regulators and diffusers from the CO2Art brand and rated for high pressure applications. Thanks to this accessory, CO2 will not escape, and every last drop of CO2 will be put to efficient use.

NB: To attach our tubing to CO2 glassware, dip the end of the tube in boiling water for 4 seconds. Wet the tip of the glassware,then simply push carefully onto the glassware. Should you feel resistance, remove and dip the tube again a bit longer in the boiling water.
