#7 Silicone Stoppers for 5-gallon (20 L) Carboys
Handy 5 and 10 Packs for your volume needs
Our premium #7 food-grade silicone bungs provide an airtight seal for standard 5-gallon (20L) glass carboys. Whether you are fermenting a batch of Cabernet or a high-gravity IPA, these bungs are heat-resistant, BPA-free, and designed to never slip out of the neck. Available in Ventilating, Bored (with hole), or Solid (Grab Ring) styles to fit your specific fermentation needs.
Airtight Fermentation: Designed specifically for 5-gallon glass carboys commonly used in beer and wine making.
High-Quality Material: 100% Food-grade silicone that won’t absorb odors or flavors; safer and more durable than rubber stoppers. Temp range is -100 to 400 F (-70 to 200 C)
Three Functional Styles:
Ventilating: Acts as a built-in airlock, releasing CO2 while keeping contaminants out.
Hole (Bored): Fits standard S-shape or 3-piece airlocks perfectly.
Grab Ring (Solid): Best for long-term aging or transport without risk of the bung being "sucked" into the carboy.
Bulk Packs: Value packs of 5 or 10 are ideal for small-scale breweries and serious home vintners.
