Description
The #6 – #7 Universal Rubber Stopper is a versatile closure designed to fit a variety of small-mouth carboys, jugs, and flasks. Made from high-quality, food-grade rubber, it provides a 100% airtight and liquid-tight seal. This model features a pre-drilled center hole, specifically sized to accommodate standard twin-bubble or 3-piece airlocks. Its unique dual-taper design ensures a snug fit for both #6 and #7 neck sizes, protecting your beverage from oxygen and contaminants during active fermentation.
Brewery Tip: To ensures a perfect seal, always ensure both the stopper and the vessel neck are dry before insertion. If the stopper keeps “slipping out,” a tiny amount of sanitizer can act as a lubricant, but drying is preferred for long-term aging. Sanitize with Star San or IO-Star before every use. This size is typically used for 1-gallon glass jugs and small laboratory flasks.
