Feature

●DRILLED RUBBER STOPPER: FastRack bungs come with a pre-drilled hole in the center sized to fit all standard-sized airlocks. The rubber bung is tapered for a better seal holding the airlock securely in place. There is a curved lip on the bung to stop it from accidentally sliding into the fermenter. Our rubber bungs have many uses in fermentation; including beer brewing, cider and winemaking.
●FOOD GRADE PREMIUM QUALITY: FastRack carboy airlock stopper is made from laboratory grade BPA free natural rubber material. These carboy bungs are sturdy, long-lasting, and great for sealing due to its heat and high wear resistance. Fits 3, 5, 6 & 6.5 gallon glass carboys.
●OUTSTANDING FEATURES: FastRack rubber stoppers drilled provide excellent grip and are air-tight on glass and other surfaces. Our tapered shape designed stoppers stay in unlike other less expensive rubber stoppers. Our high quality allows you to use our product with confidence!
●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.
●SATISFACTION GUARANTEE: At FastRack we pride ourselves on creating products that can be trusted by our customers. We manufacture our own products using state-of-the-art equipment, and following the highest standards of quality control. Each product is carefully designed by a team of laboratory professionals and experienced engineers with quality and durability in mind.
