This is our favorite dual-gauge regulator on the market. We've used them all and this unit represents the best quality at a great price. Key features are the easy hand adjusted pressure adjustment dial, barbed outlet, one way on/off valve, and built in tank connection gasket. Best of all is the consistent pressure regulation. With many regulators the pressure can 'creep' up over time. This unit is a rock. The built-in gasket where the regulator connects to the CO2 tank, eliminates the constant replacement of fiber washers every time you change out your tank. The one way valve keeps beer from flowing back into the regulator when a keg happens to have more pressure than your regulator is pushing. Grey hand dial is easily turned to adjust pressure without the need for a screw driver. Optional available gauge cage is the best on the market. Low Pressure gauge reads from 0 to 60 psi. Built by Taprite, an American company. General Regulator Information A regulator controls the flow of CO2 gas that is under pressure. To ensure proper operation, please make sure that when in use your CO2 tank and regulator remain in an upright position. Do not physically modify the regulator in any way. Regulators work best at room temperature. If you use your regulator in the cold it will take up to 4 hours for the adjustment to register. For example: If you are at 10 PSI and you change the pressure to 12 PSI the regulator will move to 14 or 15 PSI over the next 4 hours. Once you have found the correct pressure the regulator will work perfectly fine but it will take some trial and error to get it adjusted. More Tips & Tricks: 1. Are you out of CO2? When the needle reads half way in the red you are about 10% full. You should be able to push another 2-3gallons of beer when your at this amount of remaining gas. 2. What is an ideal serving pressure? For most beers a pressure set at 10-12PSI is the sweet spot. Your beer has to be stored cold from 34-40F for this pressure to work properly. 3. Is your beer serving a lot of foam? Don't panic this is not hard to fix. Your beer line must be 5-8 feet in length for this to work. Turn the black check valve to the close position (as pictured). Release the pressure from your keg's relief valve. Lower the pressure to 6-8psi by turning the flat head screw on the front of the regulator counter clock wise. Open the black check valve releasing CO2 to your keg. Try serving your beer. 4. Is my beer over carbonated? Any beer that is stored under pressure above 12psi will become overcarbonated. If you're trying to speed up the process to carbonate your beer by raising your pressure anywhere from 15-20psi make sure you don't leave your beer at this pressure for more than 2-3 days. If you did this you will need to release all the pressure from the keg before serving and set your serving pressure at 4-6psi depending the carbonation of your beer. After a week you will have to raise your pressure back to the optimum 10-12psi serving pressure.
