ESSENTIAL TWO-CHAMBER DESIGN: These classic "S-shaped" bubble airlocks are a cornerstone of homebrewing. The twin-chamber design creates a reliable liquid barrier that allows fermentation gases (CO2) to escape freely while preventing oxygen, dust, and fruit flies from entering and spoiling your brew. COMPLETE 6-PIECE BUNDLE: This comprehensive value pack includes 6 durable airlocks and 6 matching bored rubber bungs. It is the perfect solution for enthusiasts running multiple fermentation projects simultaneously, from large batches of wine to experimental cider and beer. SECURE BORED BUNG SYSTEM: Each airlock is paired with a premium, food-safe red rubber stopper. These bungs feature a tapered "long" design, ensuring a snug and airtight fit across a wide variety of glass demijohns, carboys, and plastic fermenting vessels. PROTECTIVE YELLOW CAPS: The airlocks come equipped with protective yellow caps that feature tiny ventilation holes. These caps prevent water from evaporating too quickly and act as an additional physical barrier against pests, keeping your fermentation environment pristine.
