Demijohn Bung Airlock Cap 32mm White Rubber Fermentation Stopper Home Brew Wine 1-10 Pack

This 32mm white rubber bung with hole and attached lock cap is designed for home brewing, winemaking and fermentation applications. Made from durable and flexible rubber, it fits securely into compatible demijohns and containers to help provide a reliable seal.
The centre hole is designed to accommodate a compatible airlock or fermentation accessory, allowing gases produced during fermentation to escape while helping reduce exposure to outside contaminants. When an airlock is not being used, the attached cap can be used to close the opening.
The smooth rubber construction makes the bung easy to fit, remove and clean for repeated use. It is suitable for use with our 5L demijohns with swing-top cap or without a cap.
Please note: this 32mm bung is not suitable for our screw-cap demijohns. For screw-cap demijohns, use our 28/26mm rubber bung, available separately.
Ideal for home brewing wine, beer, cider and other fermentation projects.
