Spare Catalyst Lid Seal

A secure lid seal helps maintain a controlled fermentation environment by reducing outside air exposure during active fermentation and conditioning. The silicone gasket fits around the Catalyst lid to create a tight seal while still allowing CO2 to escape through the airlock system.

The removable design also makes cleaning and sanitizing easier between brewing sessions.
