500gram CO2 bottle holder

Standard 500 gram CO2 cylinder

The 500 gram refillable CO2 cylinders come standard with a round/curved bottom and are therefore not normally suitable for standing upright. With this holder, you can be sure your 500 gram CO2 cylinder stands stable and upright.

The base of the Aqua-Noa CO2 cylinder has a round design, while the base of the Dennerle CO2 cylinder has a square bottom.
