The MK4 Dual Gauge gas regulator (Type 30 for CO2 / Post Mix Gas) is the only regulator you'll ever need to buy. With a large body and precision diaphragm, this regulator provides high flow rates and very accurate adjustments in both psi and kpa.

duotight 1.10 Design Revision

New and Improved Features
* NEW! duotight 8mm x FFL included as standard - KL06880
* Stronger Steel Gauges made from thicker steel
* Triple scale gauges in kPa, Bar and PSI
* New Colour Coded PRV valves.  This unit comes with a 65psi Green PRV.  It does not come with a Red 35psi PRV or Grey 100psi PRV
As many customers are using pressurisable fermenters such as the Kegmenters and FermZilla  units this is an important safety feature to make sure lower pressure relief valves are used for some appilcations.  Also being colour coded it's easy to identify which prv is fitted.
* New Gauge Guard S.S. for MK4 Regulator Available (sold separately)
* New M6 Mounting Holes for easy Mounting

This regulator can be used for a wide range of gasses but for other gas types a different Nut and Stem Is required.  Out of the box this regulator will be suitable for Carbon Dioxide (CO2 and CO2+Nitrogen Mixed Gasses).  However if you want to purchase this regulator for other gas types you can interchange the nut and stem with either a Type 10 or Type 50 as as shown below:
Type 10 Nut & Stem :  Helium, Argon, Oxygen
Type 50 Nut & Stem : Nitrogen

If you want to protect your investment highly recommend purchasing one of these guards:

Please note the videos are of the older MK4 that included a Swivel Nut and Barb fitting. This is no longer included in the regulator box. It now includes the KL06880 - duotight push in 8mm x FFL
