Keg Fittings & Beer Keg Accessories

Keg fittings are rarely the most exciting part of a homebrew setup, but they’re often the reason things stop working. A worn O-ring, a leaking post, a sticky PRV: none of it is complicated, but having the right corny keg fittings to hand means a small problem stays small rather than turning into a ruined batch.

At The Malt Miller we stock the beer keg accessories and brewery spares most useful for homebrew ball lock setups — predominantly for Cornelius-style 19 litre kegs, with parts covering AEB, KegLand and most other common keg brands. We’ve been helping homebrewers keep their setups running for over 15 years, so if you’re hunting down a specific part and can’t find it, drop the team a message and we’ll point you in the right direction.

For the wider kegging setup, take a look at our full range of kegs and beer dispense equipment.
