Dupla Silicone Tube, 1x3 mm

The Dupla 1x3 m silicone hose is used to supply CO2 and oxygen for use with air pumps and CO2 fertilisation systems in freshwater aquariums.

The high-quality Dupla silicone hose is gas-proof, so that carbon dioxide does not diffuse, for example, and is suitable for operating CO2 fertiliser systems and air pumps. The length can be varied by cutting.
