KLiHD 5 x Bubbler Airlocks with Red Dust Caps

This set of 5 bubbler airlocks from KLiHD provides essential fermentation control for homebrewing and winemaking projects. Each airlock comes complete with a red dust cap to keep contaminants out during the fermentation process. The airlocks fit directly into plastic demijohns or fermenters equipped with grommets, making installation straightforward. For glass demijohns or 5 gallon wine fermenters, you may need a bung to secure the airlocks properly. Filling is simple: remove the red top, hold the airlock upright under running cold water for approximately 4 seconds, then remove from the water flow and any excess will drain from the bottom. Replace the red dust cap once filled to prevent dust and dirt from contaminating your brew. These bubbler airlocks let you monitor fermentation activity whilst maintaining a one-way seal that prevents oxygen and bacteria from entering your fermenter.
