Solid Bung 37-45mm

This tapered silicone solid bung measures approximately 45mm across the top and 37mm at the bottom.

Compatibility

This is the confirmed solid bung for the 5L Glass Demijohn with Cap (SKU 50035). For any other vessel, measure the opening before ordering and allow for the bung’s taper.

This is a solid bung without an airlock hole, suitable when the vessel needs to be closed rather than actively vented. Always confirm fermentation is complete before sealing without an airlock.
