Choosing Kegerator Conversion Kits: What to Know Before You Buy

A kegerator conversion kit turns a spare refrigerator or chest freezer into a draft system, and the best kit is the one that fits your fridge, your keg size and the number of beers you want to pour. Plan around the cabinet first, then pick the tap, CO2 regulator and lines that suit it.

Check Your Fridge Before You Shop

The refrigerator or freezer you already own determines almost everything. A full-size keg is tall and wide, so measure interior height, width, depth and the position of the compressor hump or wheel wells. Many standard kegs will not fit in a typical apartment fridge once you also add a CO2 tank. Smaller formats, such as sixth-barrel and five-gallon corny kegs, are far easier to fit.

Also check how cold the unit runs. Draft beer is generally served in the mid-thirties to low-forties Fahrenheit range. A fridge with a thermostat that runs too warm or cannot be dialed in will cause foamy pours. Some builders add an external temperature controller to hold a steady setpoint, especially with a chest freezer.

Door-Mounted Taps Versus Tower Conversions

There are two common ways to get the beer out of the cabinet. A tower mounts on top of a chest freezer or through the top of an upright fridge, while a shank is drilled through the door or side wall. Towers are easier to keep cold because the beer line is surrounded by chilled air in a chest freezer. Through-the-door shanks look tidy but require drilling, so check for coolant lines and wiring in the wall first.

If you rent your space or plan to return the appliance to normal use later, a kit that requires minimal permanent modification may suit you better. Always confirm there are no refrigerant lines behind the area you plan to drill, as piercing them can ruin the unit and cause hazards.

What a Complete Kit Contains

Kits vary a lot in what they include, so read the contents list carefully. A typical complete package covers these parts:

• CO2 regulator: A dual-gauge regulator shows both bottle pressure and delivery pressure, which helps you tell when the tank runs low.
• Tap or faucet: Stainless steel construction resists corrosion and is easier to sanitize than chrome-plated brass.
• Beverage tubing and gas line: Different diameters affect flow rate and foaming. Matching line length to your pressure is part of balancing the system.
• Keg coupler: The coupler must match your keg valve type, such as a Sankey D system common on US commercial kegs or a ball-lock or pin-lock fitting on homebrew kegs.
• Shank, tail pieces, washers and clamps: Small hardware that is easy to forget until installation day.

Many kits leave out the CO2 cylinder, so factor that into your budget. If you are new to the hobby, look for a set that already bundles a regulator and lines, or browse kegerator conversion kits to compare what each includes.

Matching Kit Style to Your Setup

Pressure, Line Length and Foam

Foamy beer is the most common complaint, and it usually traces to temperature, pressure or line length rather than the faucet itself. Different beer styles carry different levels of carbonation, so the correct pressure depends on the beer and the temperature of the keg. Many brewing references publish carbonation charts that relate temperature and pressure; use one rather than guessing.

Line length creates resistance that slows the flow. Lines that are too short will pour fast and foamy, while overly long lines can make the pour slow. Beginners often start with the length recommended by the kit and adjust a foot at a time. Be patient: it can take several pours to balance a system.

Cleaning and Safety Basics

Beer lines need regular cleaning to prevent off flavors and buildup. Many owners flush lines with a cleaning solution between kegs and clean faucets periodically. A draft line cleaning kit makes this routine easier.

CO2 cylinders are pressurized containers and deserve respect. Secure the tank so it cannot fall, avoid storing it in a hot place, and ensure the area has ventilation, since a leak in a small closed space can displace oxygen. Use a spray of soapy water to check for leaks at fittings. If you plan to build more than one tap, a kegerator CO2 regulator with a secondary outlet may save you from buying a manifold later.

Common Questions

Can I use any refrigerator for a conversion?

Most fridges can work if the interior fits a keg and the walls can accept a shank. Frost-free models and units with tight compartments can complicate things, so measure carefully and confirm what is behind the walls before drilling.

How long does a keg stay fresh?

With CO2 dispensing and consistent cold, many kegs hold their quality for weeks, although this varies by beer style and how often oxygen enters the system. Using CO2 rather than room air is important for freshness.

Is a conversion cheaper than buying a ready-made kegerator?

It can be, particularly if you already own a fridge or freezer, but costs add up when you include the CO2 tank, temperature controller and cleaning supplies. Compare the full parts list against a purpose-built unit before deciding.
