Rubber Bung with Cap for Demijohn Container, Size KZ 32

The white rubber bung with a hole and locking cap is an essential accessory for any demijohn or compatible vessel. Made from high-quality, durable rubber, it provides a secure and tight seal that prevents unwanted air ingress. Thanks to its flexible design, the bung fits snugly into the neck of the container, ensuring a reliable and airtight closure.

With a precisely drilled hole, this bung is designed to hold airlocks or other attachments, making it perfect for fermentation applications. The hole allows gases to escape while blocking contaminants from entering, maintaining a clean, controlled environment for brewing, winemaking, or other fermentation tasks. The included cap lets you seal the opening securely when the airlock or other fittings are not in use.

This white rubber bung is not only practical but also simple to use and maintain. Its smooth surface facilitates easy cleaning and installation, keeping it hygienic and ready for repeated use. Whether you're a home brewer, professional winemaker, or technician, this bung offers an ideal blend of reliability, versatility, and convenience, making it a vital part of your fermentation equipment.

The 32mm bung fits our 5L demijohns, both with or without swing top caps. For our screw cap demijohns, the compatible rubber bung is the 28/26mm size (available separately).
