Our own brand Flo Clear CO2 Proof Tube is the perfect blend of simplicity and affordability. A staple item in all high-tech planted tanks, our polyurethane tubing should be the first item on your shopping list. Designed for use in pressurised CO2 systems, usually to connect a CO2 regulator to various CO2 glassware.
With an operating range of up to 155psi, this polyurethane tubing is capable of widthstanding more pressure than would ever be used in a pressurised CO2 system, giving you complete piece of mind. Furthermore, it is 100% CO2 proof and still relatively flexible, with an outer diameter of 6mm and an inner diameter of 4mm.
To attach the tubing to your glassware, it is recommended that you slightly heat the tubing using a hair dryer. This will make the tubing softer and much easier to attach to the suction cup. It is also recommended that you repeat this step when removing glassware from tubing, to prevent damage to your glassware.
