Make sense to me.  Were you able to put a gasket on each end on the outside of the sight glass inside the fitting?

I put an O Ring in the top fitting otherwise that little nipple thing that centers the sight glass would be just floating loose. I just used high temp silicone on the bottom. I think the old glass was original and it looked like it was sealed with some kind of caulking ? I'll try to post a video.
