Rubber bung with integrated pressure relief valve for 5-litre mini kegs. Vents excess pressure automatically during fermentation and storage

Mini Keg Rubber Bung with Pressure Relief Valve

A rubber bung with an integrated safety pressure relief valve for standard 5-litre mini kegs. The relief valve vents excess pressure automatically, helping to prevent over-pressurisation, excessive foaming, and structural stress on the keg during secondary fermentation or storage. A useful upgrade over the standard bung when carbonating homebrew in a mini keg.

For a bung without a pressure relief valve, see the Mini Keg Rubber Bung. Compatible with mini kegs supplied with the Brewferm Mini Keg Starter Kit.

Please note: Fits standard 5-litre mini kegs. Check bung diameter against your keg opening before ordering if using with a non-standard keg. Sold individually.
