Description
This S-bubble airlock is the preferred choice for secondary fermenters, as it allows you to monitor the pressure in the fermenter. Fill to line with boiled water or sanitizer to create a closed system, which allows CO2 to escape, but doesn't allow air back in to contaminate your wine or beer.
This top quality S type air lock has a top cap with air vent holes and "max" mark on side.
Drill a 12mm hole to fit the grommet.
Height: 170mm (approx)
