Features

• WHAT'S INCLUDED: With this purchase, you'll receive three white, pre-drilled rubber bungs designed to fit standard glass and plastic carboys. Each stopper features a center hole sized for standard airlocks, a tapered shape for a secure seal, and a curved lip to prevent it from slipping into the fermenter. Ideal for homebrewing beer, wine, mead, cider, and more.
• FOOD-SAFE & DURABLE: The FastRack carboy airlock stopper is made from BPA-free, lab-grade natural rubber. Designed for long-term use, these stoppers offer strong sealing performance with excellent heat and wear resistance. Compatible with 3, 5, 6, and 6.5-gallon glass carboys.
• OUTSTANDING FEATURES: FastRack drilled rubber stoppers offer a secure, airtight grip on glass and other fermenter surfaces. The tapered design ensures the stopper stays firmly in place—unlike lower-grade alternatives that may slip or leak. Made from durable, food-safe rubber, these stoppers deliver reliable performance you can count on throughout your fermentation process.
• HOW IT WORKS: Plug the carboy stopper into the mouth of your carboy or fermenter and then insert the airlock. This will create an airtight seal that prevents oxygen contact during fermentation. The airlock will then let CO2 escape while preventing oxygen from going back into your brewing vessel.
• OUR COMMITMENT TO YOU: At FastRack, we stand behind the quality of our products and the trust our customers place in us. Your experience matters. If your order arrives damaged or incomplete, reach out—we’ll make it right.
