I received my Immersion Pro and a pre-drilled lid last week, and I am stoked to use it. The problem, however, is that I can't create an airtight seal between the anodized rod and the lid with the parts provided.
The rod by itself has too small a diameter when using the black grommet that was set in the drilled hole in the lid; it falls right through.
The drilled white stopper, when placed on the rod, is too big for the grommet in the lid; the stopper just sits loosely on top of the grommet, and no amount of force will seat the stopper in the grommet.
If I remove the black grommet, the drilled stopper is too small for the hole in the steel; it falls right through.
Any other SS brewbucket users have this problem? If there different grommet/stopper sizes for the various fermenter lids, is it possible I was shipped the wrong sizes?
