Silicone Ventilating Bung #7 (Dry Airlock)


These stoppers create a one-way valve without any liquid, so they are
always worry-free. They also provide a superior seal, are very
durable, and can be sterilized in boiling water!

The #7 silicone vented stopper fits 3-, 5-, 6- and 6.5-gallon glass carboys.
