Spare Catalyst Lid Seal

Need another lid seal for the Catalyst Fermentation System? We’ve got you covered. 

Our Spare Catalyst Lid Seal includes a silicone gasket that comes standard with every Catalyst, but is sold a la cart if you want to keep a spare handy, or you are ready to retire an old gasket.

The seal for the Catalyst Fermentation System is specially designed to provide an airtight seal when fermenting in our 6.5 gallon capacity conical fermentation vessel. It’s designed to be removable for sanitizing purposes.

Lid seal for the Catalyst Fermentation System is photographed installed in a lid. This product does NOT include a lid.
