William’s Brewing Regulator Sale

These are included in the mix! Now is a great time to add individual control to your kegs!

Multi-Pressure CO2 Options

Maintaining multiple CO2 pressures in your kegerator gives you the ability to… keep kegs at different pressures.  This is a requirement to maintain different carbonation levels. It’s also handy if you want to force carbonate a keg more quickly, at a higher pressure, while maintaining your standard serving pressure on a keg that’s already being served or if you want to have a utility line for purging kegs and such. continues below…

The general options for pulling this off are…

  • A multi-pressure primary CO2 regulator – example. This has two (or potentially more) high pressure bodies that allow you set different pressures.
  • Secondary CO2 regulators – example. These have no ability to connect to a CO2 tank directly. They must be connected to a compatible primary.

Both good options, but generally expensive.

Kegland to the rescue. Kegland has introduced economical inline secondary regulators. As of this review there are three options.

But first, more about DuoTight!

Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing.  They offer quick, reliable connections, easy implementation, a variety of fitting options and feature amazing versatility.  They’re also, generally speaking, very well priced.  DuoTights are push to connect fittings and require no tubing clamps.

Check out my extensive Hands on Review

Hands on Review Kegland Inline Regulator w/Gauge

A look at the regulator. It has a pressure gauge, adjustment knob, inlet and outlet DuoTight ports and mounting holes.A closer look at the pressure gauge. This one goes to 60 PSI. Other gauge options may be available. This is a huge improvement vs v1. v1 feature no gauge. There is an updated DuoTight compatible inline (v2) version that has no gauge. That keeps costs down but still adds DuoTight compatibility. If you choose a model without a gauge, this is another great application of a Spunding Valve.

Kegland MK4 Two Pressure Regulator – on sale for… $82.99

Kegland MK4 Twin Gas Regulator

More Info

From the product description, check product page for current description, price and availability:

The MK4 Dual Pressure Regulator by KegLand provides a reading of keg dispensing pressure, as well as an accurate indication of cylinder gas level. By turning the center knob, you can adjust the dispensing pressure from 0 – 90 PSI. The MK4 features gauges housed in rubber to protect them from dings, as well as a large 2½” diameter diaphragm so it can both handle several kegs at once if needed, and the large diaphragm also lets you have precise control over the dispensing pressure (which you adjust with the center knob). This model has two bodies, so you can have two different dispensing pressures out of one C02 Cylinder.

Includes ¼” male flare outlets and Z93 8mm Duotight tubing adapters so you can connect either traditional threaded ¼” gas lines or 8mm Duotight tubing. Includes a safety relief valve, but does not have a check valve built into the bottom inlet. This regulator includes two nylon tank sealing washers, and will accept nylon or fiber tank sealing washers.

The high pressure gauge threads are traditional right hand, as are the threads for the lower flare outlet fitting.11½” long, this regulator needs to be attached to a C02 tank that is firmly secured to prevent it from falling over for safety.

This is a multi gas regulator, and can be used with nitrogen gas tanks if you purchase optional adapter D15.

If you want to convert this to accept 5/16″ inner diameter gas tubing (common in older kegerators), you will also need to order item D87 Concave Washer and item D08 5/16″ Swivel Barb fitting for each outlet.

 

A two pressure regulator gives you the ability to keep kegs at different pressures.  This is a requirement to maintain two distinct carbonation levels.  It’s also handy if you want to force carbonate a keg more quickly, at a higher pressure, while maintaining your standard serving pressure on a keg that’s already being served or if you want to have a utility line for purging kegs and such.

Kegland Duotight Inline Regulator (control each keg separately!) – $7.99 + free ship eligible, limited availability

Duotight In-Line Regulator D1046

Duotight In-Line Regulator via MoreBeer

More Info

From the product description, check product page for current description, price and availability:

The Duotight In-Line regulator works with both gas and liquid. Easily adjust the flow with the yellow adjustment knob. 8 mm Duotight fittings at both inlet and outlet make this unit perfect for use with EVABarrier 8 mm OD tubing (D1717 or D1718).

Suitable for applications ranging from 0-150 psi. Since this unit does not have a built-in pressure gauge, it can be used in the full pressure range without ever needing to purchase or swap out the gauge. We recommend using an adjustable relief valve/spunding valve on your keg to set the pressure.

This regulator is perfect for lowering your mains water pressure for use with the Continuous Soda Carbonator Keg Lid.

Specifications:

  • Pressure Range: 0–150 psi
  • Suitable for mains water pressure
  • Liquid and gas compatible
  • Easily disassembles for cleaning
  • 8mm (5/16″) Duotight fittings at both ends

From HBF: Make sure the components you use are compatible and rated for your intended application.  Contact manufacturer with questions about suitability or a specific application.  Always read and follow manufacturer directions.

 

Applications:

  • PET Bottles as Growlers: These are generally intended to convert 1L and 2L bottles to growlers.  Fill up a 1L or 2L PET bottle with your favorite homebrew.  Put one of these on (purge the headspace by squeezing if you want to) and then pressurize for transport.  This should help to reduce oxygen pickup and maintain carbonation levels.
  • Fine tune or rapidly carbonate beer: You can also use this cap to rapidly carbonate beer.  Same process as for transport, just set your regulator to the proper pressure and shake or agitate the PET bottle to help introduce CO2.  Or hook it up to CO2 and let it sit in you kegerator.
  • Draft Line Cleaning Projects:  I have developed three draft line cleaning projects using similar SS Caps – Build A Recirculating Draft Line Cleaning Pump | Mark II Keg and Carboy Cleaner Draft Line Cleaning Pump Conversion | Building a Simple Ball Lock Draft Line Flushing Setup
  • Related Top Post: Fun with Carbonation Caps!

Some carbonation cap models are universal fit and some work only with gas posts.  For draft line cleaning projects to work well, at least in my opinion, the carb cap that’s used needs to be universal. As of this posting, the product page says this works with both liquid and ball lock posts.  Check the product description for current specs.
