FermZilla - Replacement Lid Seal (OD 106mm x 2.65mm).
This thicker Lid O-Ring is suited to FermZilla Conical and All Rounder Models.
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.
It is also important to remember not to overtighten the stainless steel handles that may have come with your FermZilla. Overtightening will cause the opening to warp and not seal. The handles should be able to freely rotate around the neck with little resistance.
Note: this is for the seal only, lid not included.
