Bored Bung 37-45mm

A tapered silicone bung measuring approximately 45mm across the top and 37mm at the lower end, bored for an airlock.

Compatibility

This is the confirmed bored bung for the 5L Glass Demijohn with Cap (SKU 50035). Check the vessel-neck opening rather than relying on volume alone when considering any other container.

Complete the airlock setup

Fit a compatible Senior Airlock, and clean and sanitise both parts before fermentation.
