Draft Brewer Flex Homebrew Kegging System with 2 New Ball Lock Kegs
The Flex is the closest thing to an everything-but-the-CO2-tank bundle, and that is its real value: two new (not reconditioned) ball-lock corny kegs, a regulator, and snap-on tap lines, so.

Bottling five gallons of homebrew is the chore that makes people quit, so most brewers eventually switch to kegging: a Cornelius (corny) keg pressurized with CO2 that both carbonates and serves on tap. The trick is buying a ball-lock system, keg plus disconnects plus regulator, that is easy to clean and refill rather than a pile of mismatched parts. This is for the homebrewer ready to stop bottling. Here is the near-complete pick, verified budget kegs, and exactly what a system needs to pour a pint.

A few things separate a good ball lock keg system for homebrew from a frustrating one: ball lock vs pin lock, new vs reconditioned, what a system must include to pour, and food-safety and pressure. Weigh these before you buy.
- Ball lock vs pin lock: ball lock (Pepsi-style) is the US standard with the widest disconnect and parts availability, so start there; pin lock is cheaper used but uses different, less-available fittings. Do not mix the two.
- New vs reconditioned: new kegs arrive clean and leak-free but cost more; used corny kegs are cheaper but need new O-ring and seal kits plus pressure-testing before first use.
- What a system must include to pour: keg(s), a CO2 regulator, gas-in and liquid-out ball-lock disconnects, tubing, and a faucet or picnic tap. A CO2 tank is almost never included, so budget for a 5 lb tank plus a fill.
- Food-safety and pressure: buy food-grade stainless (NSF is a plus), keep spare food-grade O-rings, and never exceed the keg's rated pressure when force-carbonating.
What a keg "system" must actually include
The word system gets used loosely, so it pays to know the full parts list before you buy, because a bare keg will not pour a thing on its own. To go from a filled keg to a glass of beer you need: the corny keg itself, a CO2 tank (almost never included, budget a 5 lb tank and a fill), a CO2 regulator to set serving pressure, a gas-in ball-lock quick disconnect, a liquid-out ball-lock quick disconnect, beverage tubing, and a faucet or picnic tap. A true bundle like the Flex covers everything but the tank; a cheap keg-only listing covers just the first item. Stick to ball-lock fittings throughout so parts interchange, keep a few spare food-grade O-rings on hand since they are the usual leak point, and never force-carbonate above the keg's rated pressure.
Use this complete-system checklist before buying
A low advertised price often covers only the keg. A pour-ready system needs a ball-lock keg, an upright CO2 cylinder, a regulator, gray gas-in and black liquid-out disconnects, gas and beverage line, clamps or flare fittings, and a faucet or picnic tap. If any one of those pieces is missing, compare the total assembled cost rather than the box price.
| Check | Why it changes the decision |
|---|---|
| Keg condition | Used kegs can be good value, but budget for lid, post and dip-tube O-rings plus a pressure test. |
| Regulator protection | A shutoff with a check valve helps prevent liquid from backing into the regulator. |
| Connection standard | Keep every keg and disconnect ball-lock; pin-lock parts do not interchange. |
| Cold-space fit | Measure the keg with disconnects attached, not the bare cylinder alone. |
Source check: MoreBeer’s kegging equipment guide lists the keg, CO2 tank, regulator, gas and beverage lines, disconnects and faucet as separate required components. That is the baseline used for our bundle comparison.
What are the best alternatives?
Best verified budget keg
TMCRAFT New 5 Gallon Ball Lock Keg (NSF stainless)
An inexpensive brand-new NSF-approved stainless keg with double ball-lock posts. This listing is the keg only, so you must add disconnects, a regulator, and lines separately.

Best two-keg value
TMCRAFT 5 Gallon Ball Lock Keg, 2-Pack
Two new kegs cheaper per unit for a serve-and-brew rotation. Again kegs only, and buying new individually can approach the cost of a full bundled system.

Disconnects add-on
FERRODAY Ball Lock Quick Disconnect Set (MFL)
A cheap way to add the gas-in and liquid-out disconnects a keg-only purchase lacks. The barbed MFL fittings need correctly sized tubing and clamps, and budget sets occasionally weep until re-seated.
View on AmazonBottom line: the Draft Brewer Flex is the near-complete pick that gets a beginner pouring fast; build around verified TMCRAFT kegs plus a FERRODAY disconnect set if you would rather assemble your own. Remember the CO2 tank is separate. Pair it with our grate seasoning and grilling guides.
