Medium Drilled Universal Carboy Stopper
The Medium Drilled Universal Carboy Stopper provides a secure, airtight seal for 5–6 gallon PET plastic carboys, making it ideal for beer, wine, cider, and mead fermentation. Its drilled center hole fits a standard airlock, allowing CO₂ to vent safely while protecting your fermenting batch from outside contaminants. The tapered body and integrated lip ensure a snug, reliable fit without slipping into the carboy.
Designed for fermenters seeking a dependable and clean sealing option, the stopper’s extended taper allows it to grip firmly along the carboy opening, helping prevent leaks or accidental dislodging during active fermentation. The lip along the top adds an extra level of security, especially in high-krausen or temperature-fluctuating environments where other stoppers may loosen.
Made from durable, BPA-free silicone, this stopper resists deformation, absorbs no odors, and cleans easily between batches. Its universal sizing makes it compatible with most 5- and 6-gallon PET carboys used in homebrewing. When paired with a standard airlock, it supports a stable and sanitary fermentation environment for a wide range of beverages.
Widely used by homebrewers for its reliability and ease of use, this stopper offers consistent performance throughout fermentation.
