Double Bubble (S-Shaped) Airlock

The S-Shaped Airlock is a simple yet essential fermentation accessory for gluten-free beer brewing, allowing CO₂ to escape from your fermenter while preventing unwanted oxygen and contaminants from entering. Easy to fill with sanitizer or water, it fits securely into a stopper or grommet and provides visible fermentation activity for beginner and advanced brewers alike. When paired with a carboy or bucket fermenter, this airlock helps ensure a clean, controlled fermentation environment that supports healthy yeast activity and reduces infection risk.
