Replacement O-Ring for Fermonster Carboy Lid

Replace the o-ring on your fermonster carboy lid when the lid is no longer making an air-tight seal or when there is visible damage to the o-ring. These rubber o-rings are very thin and can be easily damaged if you over-tighten the lid. Gently hand tighten and stop when you start to feel a little bit of resistance.
