Joenos Airlock Hobby I with Fermentation Bung, 10 mm Bore

This set combines the classic Hobby I airlock with the matching fermentation bung. Together they ensure a protected fermentation: excess carbon dioxide can escape while germs and air are kept away from your batch. This lets you work cleanly and with full control.

The airlock has a 10 mm bore and fits all common Speidel barrels and many demijohns (not the 5-litre demijohn). The transparent material lets you keep an eye on the fermentation progress. As a set, it costs less than buying the items individually.
