Fermzilla -Replacement Lid O-ring

This thicker Lid O-Ring is suited to FermZilla Conical and All Rounder Models. All future models
produced after 25/12/2019 to 01/01/2023 will have these O-Rings as standard.

If you have a brown O-Ring, this is a newer material that is softer and easier to fit. All units
manufactured after 01/01/2023 will have this Brown O-Ring as standard.

If you are experiencing leaking from the top lid section, this slightly thicker O-Ring will aid in
resolving said leaking. To perform a leak test please remember to have the unit free of any liquid
as that will absorb CO2.
