U.S. Standard CGA 320 connector.

This adapter will allow you to add your existing regulator to a small (330 - 400gm)  portable C02 cylinders. 

Made of anodized aluminium, the adapter makes it easy to transport your home brew setup.

It is more suited to serving your beer (dispensing) , rather than carbonating.

Always attach the regulator in a shut off position to the Adapter before putting it on the tank.
