When you've loved your glass Big Mouth Bubbler® so much that the lid seal is starting to show wear, stocking up on extra lid gaskets and keeping them fresh ensures your Big Mouth Bubbler® will continue to produce nothing but the most delicious of homebrews.
Designed to minimize air exchange between the external and internal environment on the glass Big Mouth Bubbler®. Constructed of durable polyethylene foam, these semi-rigid seals are resistant to bacteria, mold, chemicals and solvents.
Note: These gaskets are designed for the original screw-on lid for the Glass Big Mouth Bubbler® only. They will not fit the plastic models and are not designed for use with the new Universal Lid.
