Carbonation Cap with 5/16 Barb - SS

Stainless Steel Carb Cap with 5/16 Barb fits the standard pop bottle thread and can be used to carbonate any liquid you put inside. Use to carbonate your beer, make soda water or sparkling juice. Will need a Ball Lock Gas fitting and a CO2 source.

To increase the speed at which the liquid is carbonated you can add some 5/16" tubing and a Diffusion stone to create fine bubbles of CO2 which increases the speed at which the CO2 is absorbed. Also, the colder the liquid the more CO2 it will absorb.
