#9 Silicone Bung / Stopper for small 9 gallon (34 L) demijohn & small wood barrels
Introducing the #9 Silicone Bung Stoppers, the perfect stoppers for any 5-gallon/20 L carboy. Made from premium quality food-grade silicone, these stoppers are designed to fit securely into the neck of your carboy, providing an airtight seal that helps prevent contamination, oxidation, and spoilage.
The Ventilating Bung with its unique 5-hole vent design, this stopper allows for the release of excess carbon dioxide during the fermentation process, helping to maintain a steady pressure inside the vessel. This prevents the buildup of pressure that can cause the carboy to crack or break. And because it is made from non-porous silicone, you can trust that it will not absorb any unwanted flavors or odors, preserving the purity of your wine or beer.
This stopper is incredibly easy to clean and sanitize, making it a reliable choice for both home winemakers and commercial operations. And with its durable construction, you can trust it to last through multiple batches, providing excellent value for your money.
