Pressure regulator for carbon dioxide (CO
2) for carbonating and serving. Fits directly on a
CO2 bottle, 425 g. No additional adapter is needed for use with SodaStream-type gas bottles.
Pressure gauges for remaining pressure in the CO
2 cylinder and the set pressure after reduction. The primary gauge shows the remaining pressure in the CO2 tank, graduated from 0 to 250 bar, the secondary gauge shows the reduced pressure applied to the keg, graduated from 0 to 6 bar.
Inlet connection: 21-6 ACME 2G (standard for CO2 bottle 425 g).
Outlet connection: 6 mm barb. The connected hose should be secured with a hose clamp.
If possible, choose CO2 bottles with wide and flat valve pins. Narrower valve pin designs might stay shut and not open correctly by the regulator. For the CO2 bottle to open, it needs to be tightly installed in the regulator and may require strong but gentle twisting when mounting.
The gasket which creates a seal toward the CO2 bottle will last longer if the CO2 bottle is completely empty, before dismounting the regulator.
For use with larger CO2 cylinders, consider one of ourgas regulators with standard CO2-threading (W21,8*1/14 RH) in combination with a CO2 adapter.
