Mechanical stopper for 5-liter demijohns

The reliable mechanical stopper is designed for 5 l glass demijohns and helps maintain ideal conditions for home production of wine, beer, or cider. Installation is quick and safe — simply place the stopper on the neck and press the lever down to create a firm, tight seal.

Thanks to its durable material and effective sealing, it minimizes the risk of contamination and oxidation. For maximum tightness, we recommend washing the stopper with warm water and detergent before first use and drying thoroughly to remove any manufacturing residues.

• Hermetic seal for stable fermentation without unwanted air ingress.
• Easy handling thanks to the lever mechanism — attach or remove in seconds.
• Compatibility with common 5 l demijohns (e.g., Dama 5 l, Galon 5 l).
• Durable PVC material for long service life and reliability.
