The plastic keystone bung for cask ale is designed to prevent your cask ale from spilling out the bung hole.
Keystone bung inserts easily into the bung hole on the crown of homebrew casks, fits snugly and creates a tight seal, so you can be sure you won’t lose any ale during transport.
Today plastic is very popular for Cask Conditioned Dispensing Keystone production because it is cheap, easy to clean, and doesn't attract fungal growth (unlike wooden fittings).
The central part of the keystone bung has been weakened for easy penetration of the Cask Tap.
Supplied in packs of 25
