1. Soda Co2 Refill Adapter with Pressure Gauge for Pink Co2 Cylinder 2. Soda Co2 Exchange Carbonator Fill Station Compatible with DUO Terra Art Soda Co2 Tank

Instructions for using the CO2 soda refill adapter:

1. Connect the adapter to the large CO2 tank and use the handwheel to tighten it.
2. Insert the small soda terra CO2 cylinder into the adapter's hole and close the release valve.
3. Open the valve of the larger CO2 tank. Wait for 30-60 seconds until you hear no gas flow, indicating that the filling is complete.
4. After filling, turn the handwheel to stop the flow of carbon dioxide.
5. Open the release valve to release any residual gas.
6. Remove the small cylinder.

Updated CO2 soda refill adapter: The refill adapter is only suitable for soda Terra Duo or Art soda maker CO2 cylinders in pink. Our adapter does not work with RPV valves, although some RPV valves can be removed with a hex wrench. Please check before ordering.

Easy installation: With the CO2 refill adapter, you can easily refill CO2 cartridges by connecting a commercial CO2 bottle to your pink CO2 cylinder with quick connect.

Special use for US standard tanks: The filling adapter can be used to refill small CO2 tanks from larger CO2 tanks, with the larger tanks having a US standard CGA320 thread, as found in the United States and Canada. Please note that it is not suitable for use in the UK, Germany, and other countries, as the EU standard thread is W21.8.

Safe and convenient to use: The adapter includes a pressure gauge to ensure that the pressure does not exceed the specification of the receiving tank.

Notice: For some CO2 tanks without a siphon tube, the tank must be turned upside down. When refilling, it is important to ensure that the pressure is very low in the first few seconds, so the handwheel should be opened only slightly and very slowly until some gas flows through. Please ensure that the soda CO2 cylinder is empty before refilling. Pre-cooled cartridges will be quite full.
