CO2 Tanks, Regulators & Parts

CO2 tanks & regulators are essential pieces of equipment for kegging and dispensing your homebrew.  Using a CO2 regulator to carbonate your beer exactly to the preferred carbonation level is an easy way to improve your homebrew. CO2 can be used to not only force carbonate but also push your beer from the fermenter into the keg, as well purge the keg of oxygen before filling it.  We offer multiple sizes of CO2 tanks, as well as many different CO2 regulators, manifolds and CO2 splitters.

  • Sale -20% Gauge Cage for Taprite Regulator

    Gauge Cage | For Taprite Regulator | Mounting Bolt & Washer Included

    23 reviews

    Protect your regulator from damage in the event your tank gets knocked over. A Gauge Cage is cheap insurance that can help save you a costly regulator replacement. Mounting bolt and washer included. CO2 and Nitrogen tanks, especially the 5lb size most brewers use, are notoriously wobbly and easy to knock over once the regulator is mounted on them. This handy Gauge Cage helps protect the gauges themselves, as well as the fragile points where they thread into the regulator body, from damage in case of a fall.   Specifically sized to fit our D1060 and D1070 Taprite brand ragulators, these cages may not fit some budget regulators manufactured overseas.

  • Sale -15% Secondary Regulator - 2 Way

    Taprite Secondary Regulator | 2 Way | Wall Bracket for Easy Mounting | 5/16" Barb

    4 reviews

    Perfect CO2 regulator for wall mounting in a cold box or outside of your keezer etc! Wall brackets for easy mounting 5/16” barbed outlet fittings with individual shutoff valve How do one keg of beer, one keg of sparkling wine, and one keg of root beer, sound for your next party? Awesome? Yeah, we think so too. But, each of these different beverages requires a different serving pressure, and nobody wants to go buy an extra CO2 tank and regulator for each different beverage. Enter the Secondary Regulator!   Standard multi-body CO2 regulators are heavy and can make a CO2 tank prone to tipping over, especially as it gets empty. Combine that with the fact that there aren’t Gauge Cages for multi-body regulators and you’ve got a recipe for disaster.   Secondary regulators do not attach directly to CO2 tanks, instead mounting to the side or wall of a fridge, kegerator or jockey box. They allow you run multiple keg pressures from one tank of gas. CO2 line from your existing system attaches to secondary input, and the output pressure to the keg is easily adjustable.    Features wall brackets for easy mounting. Multiple units can be purchased and ganged together, making it a snap to expand your system at any time. 5/16” barbed outlet fittings with individual shutoff valves.

  • Sale -25% Nitrogen Cartridge (1.8g)

    Nitrogen Cartridge - 1.8 g

    1 review

    Here at the shop, many of us plan on using these nitrogen cartridges to push wine out of 5 gallon soda kegs, since the nitrogen does not go into solution. You could also use them in beer situations where you want to push out but not carbonate. Please be aware that the nitrogen will only fill 20% of the space that a 12g CO2 cartridge will because Nitrogen exerts a lower partial pressure than CO2. Nitrogen has a higher PSI than CO2 so these cartridges will not work with CO2 Mini Regulators. Please note: due to air shipping restrictions, this product is only eligible for ground shipment within the contiguous United States.

    Taprite Dual Body CO2 Regulator | High Performance Primary Regulator | Independent Pressure Settings | 0-50 PSI Working Pressure | CGA320 Inlet | One Way Shutoff Valves | 5/16" Barb Outlets

    31 reviews

    High performance primary regulator designed to handle the workload of dispensing from multiple taps without freezing up! Dual body regulator for setting independent pressure settings—ideal for serving two different beer styles with different optimum carbonation levels High-pressure and double low-pressure gauges to easily reference CO2 cylinder pressure and the two output pressures Pressure settings are easily adjusted by hand using the large plastic adjustment knob CGA320 inlet features a built-in gasket where the unit attaches to the CO2 tank—eliminating the need of replacing fiber washers with each tank swap Made in the USA. Taprite is one of leading manufacturers of gas regulators and draft dispensing equipment One-way shutoff valve outlets protect your regulator from backflow and can be turned on/off to stop gas flow without needing to close your tank When it comes to CO2 regulators, we’ve tried them all. This quality unit by Taprite is our favorite on the market. It’s no wonder this regulator is trusted by so many breweries and beer bars—it represents the best quality at a great price. This dual-body model allows you to send different pressures to two separate kegs from the same CO2 tank! The things you’ll love about this regulator are:  The large front knobs make pressure adjustment tool-free, easy & fast.  A 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 barbed outlets feature one-way on/off valves which prevent backflow and protect the regulator’s internals.  The gauges are easy to read. The low pressure gauges read from 0 to 60 psi. The optional available gauge cage is the best on the market. This is the T752HP model, where the HP stands for high performance; it won't freeze up when multiple taps are running at once. Best of all is the consistent pressure regulation. With many regulators the pressure can 'creep' up over time. This unit holds the pressure rock steady. No drifting. Built by Taprite, an American company.
