This regulator can be used on a range of different gasses including CO2, Oxygen, Argon, Nitrogen and Beer Gas.

It comes fitted for CO2 with a female CGA-320 nut. To use it with a high pressure tank such as Argon, Nitrogen or Beer Gas, you will need an adapter (not included) for the male CGA-580 nut needed for those type of tanks.

The regulator has a large body for high flow rates and comes with a precision diaphragm for more accurate adjustment. The Regulator also has a large adjustment knob for easy adjustment.

MKIII is the third model of this robust regulator brought to market by Keg King of Australia.

The new MKIII regulator has all the advantages of the older MKII model but several internal improvements have been made to make the regulator even more reliable.

  • New improvements in seat and seat cap design
  • New improvements in seal composition
  • Fully encapsulated seat technology

The regulator does NOT come with a shutoff valve. You may consider purchasing and installing one: Shutoff/Check Valve

If you choose to remove the factory installed hose barb (which does not have shutoff or check), please place the regulator in a vice and use a tightly fitting box wrench to remove the barb. The shutoff/check valve should be wrapped with teflon tape and installed in the same place.

How to Use

When you first set up a draft system, it is important to pressure test the whole system. Please review the basics of pressure checking a draft system here.
