This distributor from Hiwi makes it possible to supply several aquariums with one CO2 bottle. So several diffusers or outdoor reactors can be operated with this distributor.

The distributor is equipped with several needle valves so that an exact dosage of CO2 is guaranteed.

It is connected to the pressure reducer of the CO2 source by means of an LDPE CO2-high-pressure hose. This standard 6/4 mm hose connection fits most common CO2 sources and is firmly glued to the distributor.


  • Enables you to connect several tanks to your CO2 system
  • Clamps for wall mounting included
  • Tubing connection mounted
