The white rubber bung with a hole and lock cap is an essential accessory for any demijohn or compatible container. Crafted from high-quality, durable rubber, this bung ensures a tight and secure seal, preventing any unwanted air from entering the container. Its flexibility allows it to fit snugly into the neck of a container, to provide a reliable and airtight closure. Featuring a precisely drilled hole, this bung is designed to accommodate airlocks or other fittings, making it ideal for fermentation processes. The hole allows gases to escape while preventing contaminants from entering, ensuring a clean and controlled environment for brewing, winemaking, or other fermentation activities. The inclusion of a cap seal adds an extra layer of security as the opening can be closed when an airlock or other accessories are not being used. The white rubber bung with hole and lock cap is not only functional but also easy to use and maintain. Its smooth surface allows for easy cleaning and installation, ensuring that it remains hygienic and ready for repeated use. Whether you are a home brewer, a professional winemaker, or a laboratory technician, this bung offers the perfect combination of reliability, versatility, and convenience, making it an indispensable tool in your collection of fermentation equipment. This 32mm cap is suitable for used with our 5L demijohns with swing top cap or without. If you purchase our screw cap demijohns the compatible rubber bung is our 28/26mm bung (sold separately).
