White rubber bungs are indispensable accessories for securely sealing demijohns and other compatible vessels across various uses, including winemaking, brewing, and laboratory applications. Made from durable, high-quality rubber, these bungs provide a tight, secure fit that effectively prevents air and contaminants from entering the container.

Their clean white appearance offers a professional look suitable for both personal projects and commercial operations. Available in multiple sizes (each sold separately), these bungs are designed to fit snugly within the openings of demijohns and similar containers, catering to a broad range of diameters and applications — from small-scale homebrewing to large-scale production.

Thanks to the rubber’s elasticity, the bung forms a reliable seal, preserving the contents' integrity and supporting the quality of the final product. Moreover, white rubber bungs are easy to clean and sanitize, allowing for repeated use and offering a cost-efficient sealing solution.

Whether employed in fermentation, storage, or laboratory experiments, these bungs provide a practical and efficient means to protect and maintain the contents of demijohns and other containers, ensuring consistent and optimal outcomes.
