“Converted” Ball Lock Keg -This keg was converted from a Pin Lock Keg into a Ball Lock Keg, but was also reconditioned!

These kegs have the following features:

• They are shorter than a normal Ball Lock Keg, this makes them easier to get into some kegerators.
• Feature a new lid with a pressure relief valve. This lid is normally $18.95 on its own!
• These kegs have new ball lock posts.
• These kegs are cleaned using Brew Clean a specially formulated cleaner for kegs and other homebrewing equipment.
• 22 inches tall (normal ball lock keg is 25″ tall) x 9 inches wide

Please note that these kegs are cleaned on the inside and then pressure tested for leaks. When you open the keg you might see a very small amount of liquid on the bottom and detect a slightly sweet odor. This can happen when cleaning solution drips from dip tubes. This is not residual soda, the kegs were soaked about an hour in Brew Clean and thououghly rinsed.

These kegs are in good condition, but they are used. This means they can have dings, dents and other cosmetic damage. They are serviceable and are kegs we would personally put our homebrew or other liquids in! You can return kegs, but we do not pay for return shipping.

18+ Liter Ball Lock Keg | Fully Remanufactured (AEB/SAFER/Cornelius)
These are top-tier, refurbished Corny kegs made of stainless steel. With stainless steel costs climbing and high-quality used kegs becoming increasingly scarce, this is an offer you won’t want to overlook.

Every keg in our collection undergoes a comprehensive refurbishment process. This includes deep cleaning, machine polishing, and the replacement of o-rings on the lid, PRV, as well as liquid and gas dip tubes, in addition to two o-rings on each post. These kegs are all sourced from elite brands, including AEB, SAFER, and CORNELIUS.

Additional Information on Our Refurbished Kegs:
Though these kegs are pre-owned, they may exhibit minor cosmetic imperfections such as small dings and scratches that couldn’t be completely polished away. None of these issues impact their functionality.

After the cleaning and polishing operations, some residue might be present on either the keg’s exterior or its rubber components. While it may transfer onto your hands, this is merely a reminder that all kegs—whether new or used—need to be meticulously cleaned before usage. Proper sanitization is also crucial before filling them with any beverage.

A subset of these kegs has experienced sun damage to the rubber areas, affecting the seal. This could lead to the formation of black marks, particularly when the rubber is wet, although this is less likely when it’s dry.

Lastly, you might find some kegs with double o-rings on their posts. While this may appear out of the ordinary, rest assured they function as effectively as those with single o-rings.
