A convenient wrench for tightening the CO2 pressure regulator onto a CO2 bottle. The back is to use the CO2 hose connection to rotate.
It is of great importance that the CO2 pressure regulator is good on the CO2 bottle is connected. When this is not entirely certain is tightened, can lead to CO2 escaping. Unlike a Utility or other tool, is with this CO2 open-end wrench, a piece of cake to the CO2 pressure Regulator to run.
Thanks to the eye, this wrench comes in handy in the aquariummeubel on a hook to hang.
