Twin Bubble Airlock 9mm for Wine and Beer Fermentation

A reliable double-action airlock ensures the success of your fermentation process. This classic model has proven itself among thousands of home brewers.

Technical Specifications and Compatibility

  • Suitable for 1-50 liter containers
  • 9mm standard connection port
  • 60mm rubber stopper for bottle neck

Usage and Maintenance

The airlock works as a two-way water seal, allowing carbon dioxide to escape while preventing harmful air from entering. This helps protect your beverages from:

  • Insects
  • Oxidation
  • External contaminants

Important Maintenance Information

Regular inspection and maintenance ensures effective airlock operation:

  • Check water level regularly
  • Use 10% sulfite solution instead of plain water when possible
  • Clean thoroughly after each use

Frequently asked questions about TXP0031

How much water should be poured into the water lock?

Fill the water lock to the mark between the two chambers, about halfway. Too little water will not seal properly, too much water may spill out during active fermentation. Check the level every few days, especially in warmer rooms where water evaporates faster.

Can sulfite solution be used instead of water?

Yes, a 10% sulfite solution (metabisulfite) is recommended instead of plain water. This prevents the growth of microbes inside the water lock and gives wine or beer extra protection. If sulfite is not on hand, boiled and cooled water is also suitable.

What containers is this water lock suitable for?

The water lock is designed for 1-50 liter containers. The Ø60mm rubber stopper fits standard glassware and cylinders, and the 9mm connection hole fits most homebrew caps and seals.

Why doesn't my water lock appear for me?

Absence of bubbles may mean that fermentation has stopped, the temperature is too low, or there is an air leak at the cap. Check the tightness of the rubber cap, the water level and the fermentation temperature before you think the process has stopped.

How to clean the water lock between batches?

Open the water lock, rinse with warm water and clean with brewing detergent or mild detergent. Make sure the chambers are free of sediment and disinfect before the next fermentation to avoid cross-contamination between batches.
