Kegs With Ball Lock - Cornelius

Ball lock kegs, the Cornelius type, are the reason home kegging took off. They seal properly, they stack, and every part on them can be replaced, which is why a keg bought second hand is usually just a keg that needs new O rings.

Start with the vessel. The 20 L beer keg with a plastic shell and ball lock is the everyday size, the 2 L ball lock keg suits a taster batch, and the Mangrove Jacks mini beer keg comes with its own tapping head. After that it is all serviceable parts. The ten piece O ring set to suit Cornelius type ball lock posts is the first thing to buy, because posts and lids leak long before anything else does. Stainless liquid and gas posts are sold separately, including a gas post with the F19/32 thread and a liquid ball post for Mytton Rod and Rheem kegs with no groove. Poppets and springs, T bar keg opening tools, a grey 100 psi pressure relief valve, plastic and MFL disconnects, a yellow multi liquid carbonation cap and a keg to keg daisy chain disconnect fill in the rest.

Before you chase a leak around with soapy water, just replace the lid seal. It is the cheapest part on the keg and it is the culprit most of the time.

We keep kegs and spares at Laverton North and Epping. See also keg accessories, taps and faucets and CO2 tanks and regulators.

Frequently asked questions

What is a ball lock (Cornelius) keg?

A stainless keg with two ball lock posts, one for gas in and one for beer out, and a large lid that makes it easy to clean and fill. It is the standard keg for home brewers who want to carbonate and serve their own beer.

What size keg should I buy?

A 19 L keg is the usual choice for a standard 20 to 23 L batch, once you leave the sediment behind in the fermenter. Mini kegs from 2 L to 10 L are handy for small batches, splitting a batch, or taking beer to a party.

What else do I need to start kegging?

A CO2 cylinder and regulator, gas and beer disconnects with line, and a tap or beer gun to pour. To keep it cold you will want a fridge or kegerator. See our CO2 tanks and regulators, keg couplers and beer line and kegerators.

Can I replace the seals on my keg?

Yes. O-rings wear over time, and we stock complete O-ring seal kits for Cornelius ball lock kegs as well as post, lid and dip tube seals. A fresh set of seals fixes most slow gas leaks.
