#7 Solid Rubber Stopper

The #7 Solid Rubber Stopper is an essential accessory for homebrewers, designed for sealing fermenters, carboys, or bottles in the brewing process. It is compatible with various vessel sizes, ensuring a snug fit to prevent contamination and maintain your brew’s integrity.

To use, ensure the stopper fits securely in the neck of your fermentation vessel. Sanitize the stopper before and after each use to maintain hygiene. For effective fermentation, create an airlock system using a water lock or airlock valve to allow carbon dioxide to escape while keeping air from entering.
