The Add-On CO2 Regulator Adapter allows you to join two CO2 regulators together for dispensing two beers that require different CO2 pressures.
Simply remove the high pressure gauge from one regulator and screw this adapter. Then attach your other regulator directly to the other side of this adapter.
The two threads are 1/4" NPT and Type 30 UNF. Designed to suit the MKIII/MK4 CO2 Regulator but will fit most CO2 regulators.
Note: does not include regulator or gas bottle.
