Description
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.

26th Jun 2025Does what it says on the tin. Feels solid and refills my cylinder bottles without issue. Would be 5 stars if it included some printed instructions (but they are on the website).
