Simply remove the cylinder pressure guage of the first regulator. Install the adapter and then attach the second regulator. Lets one gas cylinder be used for beer while also being used to gas pre-mix or flavoured soda water etc. This adapter may not fit Harris, CIG, Macromatic, or Imake regulators.
