This Hiwi branch enables you to supply several tanks with one CO2 cylinder. It comes with an integrated check valve in the needle valve, which secures the CO2 System from back running water. Several diffusers or external reactors can be run on this CO2 splitter.

The branch is equipped with several needle valves that guarantee a precise CO2 dosage.

In order to put the branch into operation, you connect the branch with tubing. A 6/4 mm tubing connection is mounted as a standard and fixated with glue. With a CO2 high pressure tube (for example LDPE or PURE) the connection to the pressure reducer is made.


  • Branch with integrated check valve in the needle valve
  • Enables you to connect several tanks to your CO2 system
  • Clamps for wall mounting included
