I'm beginning to think that welding a threaded coupler into the vessel well, threading the pickup tube into it on the inside and threading a tri clamp flange to it may be the way to go.
However, if you are going to do that, why not skip the triclamp flange and thread a threaded valve onto the coupler ? ie one of these ?1/2" Stainless 3-Piece Ball Valve from Brewers Hardware
I thought the purpose of triclamp was to get rid of threads because they can't really be cleaned internally. I thought the system was supposed to go triclamp -> tubing with no threads.
Once you have a thread in the system, its harder to clean.
