Ar/O/He MK4 Dual Gauge Multi Gas Regulator
This is the regulator with the Type 10 for Argon, Oxygen and Helium gas.  With a large body and precision diaphragm, this regulator provides high flow rates and very accurate adjustments in both psi, bar and kpa.
The most common problem with regulators sold on the market was that contamination would occur through the seat and cap assembly within the regulator.  This has now been solved with a second sintered filter on the underside of the seat assembly, within the regulator, to block contaminants.

New and Improved Features
* Stronger Steel Gauges made from thicker steel
* Triple scale gauges in kPa, Bar and PSII
* New Colour Coded PRV valves.  This unit comes with a 65psi Green PRV.  It does not come with a Red 35psi or Grey 100psi PRV
As many customers are using pressurisable fermenters such as the KegMenters and Fermentasaurus  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 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 Type 10 threaded gas bottles.  However if you want to purchase this regulator for other gas types you can interchange the nut and stem with either a Type 30 or Type 50 as as shown below:
Type 10 Nut & Stem :  Helium, Argon, Oxygen
Type 30: Carbon Dioxide

If you want to protect your regulator we highly recommend getting one of these Gauge Guards.
