  • The MK4 Dual Gauge Gas Regulator (Type 10 for O₂ / Argon / Helium) 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 kPa, Bar and PSI. The build quality and value simply cannot be beat.


    Improvements over the MK3 version include:

    • NEW! duotight 8mm x FFL included as standard
    • Stronger Steel Gauges made from thicker steel
    • Triple scale gauges in kPa, Bar and PSI
    • New Colour Coded PRV valves*
    • New Gauge Guard Available (sold separately)
    • New M6 Mounting Holes for easy Mounting

    * This unit comes with a 65 PSI Green PRV.  It does not come with a Red 35 PSI or Grey 100 PSI PRV. As many customers are using pressurizable fermenters, such as the Fermenter King Junior that we offer, this can provide an additional layer of safety to ensure lower pressure relief valves are used for these applications.

    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 Oxygen, Argon, and Helium.  However if you want to purchase this regulator for other gas types you can interchange the nut and stem with either a Type 30 Carbon Dioxide (CO₂ and CO₂+Nitrogen Mixed Gasses) or Type 50 (Nitrogen) nut and stem.
