Description

Specially designed from ether based polyurethane (PU), this tubing ensures minimal gas permeation, significantly reducing CO₂ waste and providing stable, consistent carbon dioxide delivery to your aquarium plants.

Why Choose Our CO₂ Tubing?
  • Superior Efficiency: Minimize CO₂ leakage and maximize your system's effectiveness.
  • Durable and Reliable: Constructed from ether based polyurethane for long-lasting performance.

  • Safe & Aquarium Friendly: Completely safe for freshwater planted tanks, with no risk of contaminants.
  • Custom Lengths: Sold conveniently by the meter—simply order the exact amount you need for your setup.
Why Avoid Silicone Air Tubing?

Regular silicone airline tubing, commonly used in aquarium air pumps, is unsuitable for CO₂ systems as silicone allows CO₂ to permeate through its walls. This permeability leads to inefficient gas usage, inconsistency in CO₂ delivery, and ultimately higher operating costs.

Specifications:
  • Material: Polyurethane (PU), Ether-based PU, medium durometer (~90A) : Medium flexible / springy
  • Dimensions: Standard 4mm inner diameter / 6mm outer diameter
  • Colour: Clear, discreet design

Perfectly suited for all CO₂ injection systems.

Packaged poorly

It's okay but was packaged such that there are kinks all throughout the tube

Does what it says it does.

Good tube quality for the price!! Nice and thick so it can handle the higher co2 pressures. Haven’t had any issues with the hose or leaks around the ends.

Great tubing, much thicker than airline tube - which gives a bit more comfort regarding pressurized co2!
