The Hex - 3 Piece Airlock

$3.79
Durable BPA-free 3 piece fermentation airlock designed to release CO2 while protecting beer, wine, mead, and other fermentations from outside contaminants.
  • Durable thick-walled BPA-free plastic construction
  • Allows CO2 to escape while blocking contaminants
  • Shatter-resistant hexagonal chamber design
  • Gold piston improves fermentation visibility
  • Easy to disassemble, clean, and sanitize

Fill the airlock chamber with sanitized water or airlock solution to the recommended fill line. Insert the airlock into a compatible drilled rubber stopper or fermenter lid.

As fermentation progresses, CO2 bubbles will pass through the liquid barrier while helping prevent outside oxygen, bacteria, and debris from entering the fermenter.

Clean and sanitize thoroughly before and after each use.
