Hi Matthew,
The o-rings are 8mm ID x 2mm section, definitely Viton and are 70 - 75 Shore D (which I believe is normal for Viton O-rings). I can get the feeler gauge part way in until it touches what I assume is the squashed O-ring.
The opposite side, with the dome nut, seems OK because this has a double chamfer for the o-ring to go into (one on the washer, and one on the case).
Doesn't seem right to me that is the way it is supposed to work
