This is the Dual Pressure MK4 CO2 Regulator - you'll find the single pressure regulator here.
Need to set two different CO2 pressures for different beers on tap? Then you'll need two regulators to do it properly. With this MK4 Dual Pressure Regulator you'll be able to screw it into your CO2 bottle and fire away with two different pressures. No need to removing the High Pressure gauge off one regulator, buying an attachment and joining the two together.
This new MK4 Model regulator has several advantages including:
1. Safer design with colour coded pressure release valves
2. Easy mounting option
3. Optional extras such as gauge guard
4. Better body design and more reliable
Now comes with Duotight 8mm push-fit fittings rather than barbs as in photo.
Note: CO2 bottle not included.
