Practical rubber stopper TECH No. 1 for hermetically sealing bottles, demijohns, and containers during home beverage production. Thanks to its tapered shape, it reliably adapts to the neck, providing a tight and secure closure, and the hole allows connection of a fermentation airlock for efficient gas release during fermentation. Made from high-quality, non-absorbent rubber that does not affect the taste or aroma of the beverage.
The TECH No. 1 rubber stopper is an ideal choice for home winemakers and brewers. The tapered profile ensures universal fitting into various neck diameters, while the precise hole for the airlock enables safe, controlled fermentation without the risk of contamination. The material is resistant to temperature changes and common cleaning agents, making it suitable for repeated use.
Main advantages:
- Tight, hermetic seal for stable fermentation without unwanted air ingress.
- Hole for a fermentation airlock for safe CO2 release and overpressure prevention.
- Neutral material – the rubber does not react with the beverage and does not affect taste or aroma.
- Easy maintenance and long service life thanks to resistance to temperatures and chemicals.
- Universal tapered shape for containers within the appropriate neck diameter range.
This stopper is a great accessory for demijohns and fermentation vessels where controlled fermentation and a clean, safe environment are required for producing wine, beer, or musts.
