Adapter drinking water carbonator to CO2 bottle thread.
Use your drinking water carbonator CO2 cylinder as a CO2 source and use your existing CO2 controller without any modification.
The adapter converts the trapezoidal thread of a drinking water cylinder into a CO2 bottle thread W21.8 according to DIN 477 No. 6.
This is not a transfer adapter.
Instructions can be found here in the pictures.
With the adapter, you can connect a standard CO2 pressure regulator to a standard 425g/60l drinking water CO2 cylinder.
So you can also operate your existing beer dispenser or the aquarium pressure regulator with drinking water CO2 cylinders.
The adapter is simply screwed between pressure regulator and drinking water cylinder.
The input of the adapter is suitable for all drinking water cylinders with coarse trapezoidal thread.
The length of the inner valve pin can be adjusted by simply turning to different soda cartridges.
An internationally standardised CO2 bottle thread (W21.8 x 1/14 inch) is available for connection to the outside.
The internal seal ensures leak-free installation.
Instructions:
Please note: once the adapter is screwed onto the CO2 cartridge, it can no longer be closed. Therefore, always connect the drinking water adapter to your CO2 pressure regulator first gas-tight. Use a wrench if possible and pay attention to a secure seal.
Open the pressure regulator by screwing back the adjusting screw for pressure adjustment. This prevents a sudden increase in pressure in the controller during connection.
Hold the cartridge securely with your hands while now tightening the adapter to the cartridge with a wrench.
Please put on gloves
