rubber plug with pressure relief for minikeg 5L

Specially designed stopper for 5L Mini kegs and Mini kegs with tap, allowing the use of a suitable holder for serving beer with CO2.

These rubber stoppers with valve allow excess carbon dioxide to escape automatically during refermentation, while maintaining a pressure of approximately 2.5 bar. This means that your Mini Barrels will no longer be inflated!

The stoppers are reusable.
