Description:

• The 3-Piece airlock is the best choice for  the primary fermenter, since it comes apart for easy cleaning in the event of a  blow-off. Fill to the line with boiled water or sanitizer to create a closed  fermenting system that allows CO2 to escape, but does not allow air back in to  contaminate your beer or wine.
• Size: 12 x 9CM
• Interface: 9-13MM

Package Includes:

• 1x Exhaust Valve
