CO2 Cylinder Refilling Adapter

The CO2 Refilling Adapter is used to safely refill cylinders from larger donor cylinders. It is designed to connect to either a CGA 320 or DIN 477 / W21.8 / BS 341 No. 8 donor cylinder, and then connect either directly or via a high pressure hose to the recipient cylinder.

The Refilling Adapter is designed to allow refilling of DIN 477 / W21.8 / BS 341 No. 8 CO2 cylinders, or you can add an adapter for refilling of SodaStream or Paintball / CGA 320 cylinders.

The refilling adapter also includes a pressure gauge to ensure the pressure of the donor cylinder will not exceed the pressure specification of the recipient cylinder.

The refilling adapter also has a dump / purge valve to safely release the residual gas within the adapter once refilling is completed.

Instructions

• Connect the refill adapter to the parent / donor cylinder.
• Screw the connection hose into the refill adapter.
• Screw the cylinder into the end of the connection hose.
• Open the valve on the parent / donor cylinder to release the gas.
• Turn the shutoff valve to release the gas.
• Open the valve on the CO2 cylinder to inject gas into the cylinder. You will hear gas flowing into the cylinder.
• The pressure gauge will slowly increase as the cylinder fills.
• Once refilling is complete, stop the CO2 by turning the shutoff valve.
• Close the valve on the recipient CO2 cylinder.
• Release the residual gas by opening the dump / purge valve.
• Remove the cylinder from the connection hose. Repeat the refill process for each cylinder.
• Once finished, close the valve on the parent / donor cylinder.
