The MKIII Dual Gauge gas regulator (Type 50 for N2 (Nitrogen) is the only regulator you'll ever need to buy for any stout or non-carbonated cocktail dispensing system. With a large body and precision diaphragm, this regulator provides high flow rates and very accurate adjustments in both psi and kpa.

Nitrogen MKIII Dual Gauge Multi Gas Regulator

The Type 50 for Nitrogen - MKIII Dual Gauge gas regulator is the only regulator you'll ever need to buy for a deluxe nitrogen stout/cocktail setup. With a large body and precision diaphragm, this regulator provides high flow rates and very accurate adjustments in both psi and kpa.

The most common problem with other 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.
- Ultra-high molecular weight polyethylene seal (UHMWPE).  The new UHMWPE is far superior in chemical resistance and stability than other big brand names that use Teflon.
- 0 - 50 PSI recommended working pressure (higher pressure guages and RPV can be fitted to make this model go up to 100 PSI)
- 1/4 in MFL outlet (so it uses the same as your ball lock disconnects, it is also compatible with this )
- Improved seat and seat cap design
- Fully encapsulated seat assembly helps prevent contamination
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 Nitrogen.  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 10 as as shown below:
Type 10 Nut & Stem : Argon, Oxygen, Helium
Type 30 Nut & Stem : CO2, CO2/Nitrogen Mixed Gas
