Keep your fermentation system sealed and performing properly with the Spare Catalyst Lid Seal, a replacement silicone gasket designed specifically for The Catalyst Fermentation System. This removable lid seal creates an airtight connection between the fermenter lid and tank to help protect beer, wine, mead, cider, and other fermentations from oxygen exposure and contamination during active fermentation. Made from durable food-grade silicone, the gasket is reusable, easy to sanitize, and built for repeated brewing cycles.
Designed exclusively for The Catalyst Fermentation System, this replacement gasket matches the original lid seal included with every Catalyst fermenter. Its flexible silicone construction helps maintain a reliable seal while remaining easy to remove for cleaning and sanitizing between batches.
This product includes the silicone lid gasket only and does not include the fermenter lid or tank. Ideal for replacing worn seals or keeping a backup on hand during cleaning and maintenance.
Widely used by homebrewers maintaining The Catalyst Fermentation System, this replacement lid seal helps support consistent fermentation performance and secure fermenter operation.
