This innovative demijohn stopper (Ø26/28 mm) is ideal for sealing carboys and fermentation bottles. The stopper features a permanently attached, closable opening for an airlock, making it perfect for use during and after fermentation.
The integrated click closure allows the opening to be sealed airtight after fermentation. The audible “click” ensures the stopper is securely closed.
The stopper is made of durable and flexible thermoplastic elastomer, providing an excellent fit and long-lasting use. Thanks to the special flange, the stopper is easy to remove and prevented from slipping into the bottle.
