🍺 Seal your brew like a pro—no leaks, no worries!
This pack of three white, pre-drilled rubber stoppers is engineered for homebrewers using 3 to 6.5-gallon glass carboys. Crafted from BPA-free, lab-grade natural rubber, each stopper features a tapered shape and curved lip to ensure a secure, airtight seal that prevents oxygen exposure and slipping during fermentation. Compatible with standard airlocks, these durable stoppers deliver reliable performance for beer, wine, mead, cider, and more.
