Item #: KEYSTONE-PLASTIC
Prevent your cask ale from spilling out the bung hole by using this wooden keystone cask bung.
It inserts easily into the bung hole on the crown of your pin cask or firkin beer cask. The wood absorbs moisture to help create an extra-tight seal. This maintains your beer's quality over time.
The keystone bung hole of your cask is essentially the same as its tap. If you don’t plug it up, the ale will flow, so add this wooden keystone cask part to prevent unwanted beer spills.
