CO2 Regulator w/2 low pressure, 1 high pressure gauge, 5/16" Barb
This is the perfect regulator if you would like to serve at different pressures at the same time. Has one high pressure gauge that tells you how much CO2 is left in your tank and two low pressure gauges, which allow you to set a different pressure for different CO2 lines.
Each low pressure regulator has its own pressure relief valve and a 5/16" barb with a shut-off.
Note: The high pressure gauge will not read properly if you keep your CO2 tank in the refrigerator.
