Pack of 6 North Mountain Supply #6.5 drilled rubber stoppers made from high quality custom blended materials. Designed for slip resistance and a reliable airtight seal, these stoppers fit all standard size fermenting airlocks and are ideal for fermentation setups.
North Mountain Supply #6.5 drilled rubber stoppers are designed to provide a dependable seal for fermentation vessels that use standard airlocks. This pack includes 6 matching stoppers, making it a practical choice for homebrewers, winemakers and fermenters who run multiple batches or want spare bungs on hand.
Each stopper is made from high quality custom blended materials and is specifically designed to offer:
Slip resistant performance for a more secure fit
A reliable airtight seal during fermentation
Compatibility with all standard size fermenting airlocks
The pre-drilled opening allows you to insert a standard fermentation airlock easily, helping CO2 escape while limiting outside air exposure. This makes these stoppers well suited for use with:
Glass carboys
Fermenting jugs
Wine and cider vessels
Other compatible fermentation containers
Because a tight seal is essential for controlled fermentation, the slip resistant design helps keep the stopper seated more securely in the vessel opening during active bubbling and pressure changes.
