Airlock – 3 Piece
Airlock – 3 Piece is ideal for sealing your fermenting vessel and allowing CO2 to vent. Easy to take apart and clean and easy to use.
Includes body, piston, and vented cap.
Fill to line with boiled (and cooled) water or sanitiser to create a closed system, which allows CO2 to escape, but doesn’t allow air back in to contaminate your wine or beer.
Please note that grommets are sold separately.
