This package is used to convert your iKegger Nitro Coffee tap system to one that has a mini CO2 regulator, enabling it to be used with beer, cider, soft drinks etc.
In order to use it you will need a spanner to remove the valve gas inlet and replace it with a ball lock quick connect post.
Onto that you can then attach the professional mini regulator using a ball lock disconnect.
This package includes the gas post, the regulator and the gas disconnect to attach the regulator to the post. (It does not include the keg and tap system, just the pieces beside the keg in the picture)
