This high-quality pressure regulator by Hiwi is specially designed for the use on Sodastream Cylinders. It is operated to reduce the pressure inside the cylinder to a working pressure of approx. 1 to 3 bar. By combining the working pressure manometer and the cylinder pressure manometer you can regulate the CO2 supply very precisely and you know at once when it is time to change the cylinder. The integrated fine needle valve allows a very precise regulation of the CO2 supply for the aquarium. In addition, a check valve secures the pressure regulator from back running water.

Please keep in mind that all components of the pressure reducer have been glued together by the manufacturer. These can not be unscrewed without damaging them. If the needle valve is removed, the manufacturer's liability will expire prematurely. The hose connection on the fine needle valve is an exception. This is not glued in due to the fine thread, so that in the event of a defect, it is not necessary to replace the entire fine needle valve but only the hose connection.


  • The connection for the CO2 tubing is equipped with a metric thread (M6)
  • The pressure regulator is designed for Sodastream Cylinders only
  • No special adapter necessary
  • Seal included
  • with German instructions of use

Hiwi is a renowned German manufacturer of CO2 pressure regulators. The highest level of quality and a long useful life are in their focus. These high quality standards do not exclude attractive prices, though.

Especially in aquascaping, the addition of CO2 for the plants is something very basic, and thus it is really important to choose good CO2 supplying equipment. Hiwi meets even the highest quality standards in every aspect und is thus the best choice when it comes to CO2 pressure regulators.
