Solid Rubber Bung — Standard Demijohn & Fermenter Bung
A solid rubber bung sized for standard demijohn and wide-neck fermenter necks. Rubber is more durable and slightly less prone to infection than natural cork, making it a reliable choice for long fermentations and extended maturation. If you need to fit an airlock, see the Bored Rubber Bung instead.
Please note: This is a solid bung — it does not have a hole for an airlock. For an airtight seal during active fermentation with an airlock fitted, use the Bored Rubber Bung (Demijohn Bung).
