Ah yes, thanks Drew, I see the difference in that flange. The second one I posted last night looks a bit simpler and has an 8" CF on each end. It's this one:
I would probably want to put a blank on one end and use that for the bottom, and a view port on the top, then plumb the 2.75" CF on the side down to the pumping system.
What do you think?
Thanks,
-Dave

It looks ok except for that top most interface.? with only 4 bolts across what looks to be 6" dia I am not sure that is a "fitting" interface.? It may be expecting to be bolted down to a thick plate like the top of a cart that holds your vacuum system.
I will look thru my collection of stuff for that flange in case you get that thing.
