An ideal solution if you want to serve different beers at different gas pressures. In a typical multiple line, multiple pressure system you would run a gas line from you main regulator into a secondary regulator where you would set different pressures. While that is ideal it is a little pricey. This little sweetheart lets you set different pressures at a far lower cost. What we do is set the main regulator at the highest pressure we want in the system – for example a keg of soda that you want to carbonate and serve at 25 psi. Run the gas line into a manifold and then install one of these after the manifold on each line where you want to decrease the pressure, for example lowering to 10psi to serve your British pale ale and 14 psi to serve your summertime lawnmower lager.

While this unit does not have a pressure gauge you can use an adjustable relief valve/spunding valve on your keg to tell the pressure. Pressure adjusments can be made with a screwdriver.

The maximum inlet pressure is 150 psi. Made from non corrosive acetyl, nitrile, and stainless parts. The regulator comes with two brass barbs to fit 3/16″ tubing on. Alternatively, you can remove the barbs and use 1/4″ tubing directly on the regulator. The aluminum manifolds linked above feature 1/4″ barbed outlets and are a good match with this regulator.

  • Works with 0 – 150 psi
  • Works with both gas and liquid
  • Comes with two brass barbs
  • Has two mounting points
  • Made from non corrosive acetyl, nitrile, and stainless parts


But Why??

  • This thing is awesome: This is an inline secondary regulator.  You still need a primary regulator attached to your CO2 tank.  The idea is, you set the primary to the highest pressure you will use (without exceeding specifications of any component of your system) and then use these regulators inline (one per line) to fine tune pressure and carbonation [See: Balancing Your Draft System].  As an example, you could set your primary to 25 PSI for faster force carbonation and set each line to a different pressure based on desired carbonation level.  Since this does not have a gauge, you need some sort of a gauge to use for tuning this in.  The gauge doesn’t have to stay connected, just while you’re setting the regulator.  This is a perfect application of a Spunding Valve [See: Build a Spunding Valve! – How and Why]
