I just re-edited my original post with the following addition:
Edit 6/25/2018 - After a year in service I had a VERY difficult time removing the glascolator bowl for my condition inspection. So hard that I was going to go back to the standard Andair o-ring, but when I installed one it was so loose that it reminded me why I started this investigation to begin with. I ended up re-installing a 2.5mm X 36mm o-ring and used fuel lube to lubricate it. I will report back next year. I would not recommend installing this o-ring without lubricant and I can't say for sure if lubricant will fix the removal issue.
