This double gauge nitrogen regulator is used for dispensing draft beers like, Guinness Stout, Murphy's Stout and Boddingtons. Similar in appearance to a CO2 regulator, the notable difference is the nitrogen tank compatible threading. With two gauges this kegerator regulator can display the pressure going into the keg and also tell you how much nitrogen is left in your air tank. This nitrogen regulator provides distribution for one keg and is equipped with a nonadjustable "shut down" that blows off excess gas at 55-65 PSI. There's also a convenient air shut off switch for when the gas tank isn't in use. Features: 2 gauges measure pressure in tank and out. O-Ring inlet seal at tank connection. Set screw pressure adjustment. Flow control inlet nipple filter. Safety valve with manual bleeder valve.
