Rubber bungs are used when fermenting to completely seal or create an airtight barrier between the airlock and opening of your fermenter.
Depending on your needs you have two options: Solid Rubber stoppers create a complete seal while drilled rubber stoppers have a hole drill into them which fits a standard size airlock or a small blow-off tube.
Rubber stoppers come in assorted sizes and are required to create an airtight seal in most fermentation. Our food-grade stoppers are made of solid rubber. The rubber bung is tapered for a better seal and holds the airlock securely in place. The curved lip also stops the bung from accidentally sliding into your fermenter. These stoppers have many uses in fermentation which include beer brewing, cider, and winemaking, just to name a few.
The solid rubber stopper is one of the most basic tools for homebrewers of all experience levels to have on hand. The rubber stoper fits perfectly into your fermentation vessels to create an airtight seal for your fermentations and homebrews.
Plug the stopper into the mouth of your carboy or fermenter. This will create an airtight seal that prevents oxygen contact during fermentation.
The food-grade rubber and design of the solid rubber stoppers keep the stopper in place and create an airtight seal on top of your brewing vessels.
Stoppers come in various sizes and are sized by number but what do these numbers mean? To determine the correct stopper size, measure the diameter of the mouth of your carboy or fermenter, and compare it to the rubber stopper size chart below. This chart will help you quickly determine which stopper you need by most popular brewing equipment and provides a diameter for each stopper style in inches.
