Description:
CO2 tubing is the essential link between your CO2 system and your diffuser or reactor. Standard airline tubing is not suitable for CO2 use as it is too permeable and allows CO2 to escape through the walls before it reaches your diffuser, reducing efficiency and wasting gas. This tubing is specifically designed for CO2 applications, made from a denser, less permeable material that keeps CO2 contained and delivers it efficiently from your regulator to your diffuser.
This 3 metre CO2 tubing has a 4mm inner diameter and 6mm outer diameter, compatible with most standard CO2 regulators, diffusers, and check valves. Made from high-quality, non-toxic plastic, it's odourless, safe for planted tanks and invertebrates, and flexible enough to route around your tank without kinking or deforming. The transparent material makes it easy to monitor CO2 flow and spot any bubbles or blockages in the line.
The 3 metre length gives you enough to run from your regulator to your diffuser with room to customise the routing to your setup. Suitable for use across a temperature range of -5°C to +70°C.
Suitable for planted freshwater aquariums running CO2 injection systems.
Product Features:
- Made from thick, high-quality material that is safe and odourless.
- Allows easy monitoring of CO2 flow and system performance.
- Can be easily bent and folded without deforming, ensuring long-lasting use.
- Customize the length to fit your aquarium setup perfectly by cutting the tube.

How the CO2 Tubing Compares
💨 CO2 Tubing
- 🔒Designed for CO2: Made from a denser, less permeable material designed to help keep CO2 contained as it travels from your regulator to your diffuser or reactor.
- 💨Helps Reduce CO2 Loss: Lower permeability helps minimise CO2 escaping through the tubing walls before it reaches your aquarium.
- 📏3 Metre Length: Provides plenty of tubing for routing from your CO2 regulator to your diffuser, with the flexibility to cut it to the required length.
- 🔍Transparent Design: Makes it easier to monitor the line and identify bubbles, blockages or other issues.
- 🔧Flexible & Easy to Route: Can be bent and routed around your aquarium setup while maintaining its shape, making installation easier.
💧 Standard Aquarium Airline Tubing
- 💨Not Designed for CO2: Standard airline tubing is intended for air rather than pressurised CO2 injection systems.
- 💨More CO2 Permeable: Allows more CO2 to pass through the tubing walls, which can reduce the efficiency of a CO2 injection system.
- 🔧Better Suited to Air: A practical choice for air pumps, sponge filters and airstones rather than dedicated CO2 applications.
- ⚙️Less Suitable for Pressurised CO2: Using tubing designed specifically for CO2 helps ensure the gas is delivered efficiently through the system.
- 💸Lower-Cost Option: Standard airline tubing can be inexpensive, but using it for CO2 may result in unnecessary gas loss over time.
CO2 tubing is one of those components that's easy to overlook when setting up a CO2 system, but using the wrong tubing costs you CO2 efficiency and money over time. Having the correct tubing on hand means your CO2 is getting where it needs to go rather than slowly diffusing through the walls of a standard airline.
Inspect CO2 tubing periodically for kinks, discolouration, or reduced flexibility. Replace sections that show signs of wear. Cut cleanly with scissors for a secure fit on connectors. You can test for leaks using a mild soap along the airline tube whilst your CO2 system is running; if you see bubbles along the airline there is a leak and your airline may need to be replaced to prevent CO2 loss.
