#2 Solid Rubber Stopper

The #2 Solid Rubber Stopper is designed specifically for homebrewing applications. It is utilized in various fermentation processes to seal vessels while allowing gas to escape, preventing contamination and ensuring optimal brewing conditions.

For effective use, ensure the stopper securely fits the neck of your fermentation bottle. It is compatible with standard-sized glass or plastic fermenters. Clean the stopper before and after each use to maintain hygiene, and replace it if you notice signs of wear or degradation to ensure a proper seal during fermentation.
