Good day all! I am currently building an electric brewery setup in my garage (thread here).
I'm using converted kegs for my brewing vessels, and one thing I'm having trouble deciding is just which style of weldless bulkhead to use for all my fittings.
It seems that most of the major suppliers (Bargain Fittings, Brew Hardware, etc) have a similar kit:
1/2in close nipple, an O-ring of some sort, and a coupling or elbow for the inside of the keg.
If I go by TheElectricBrewery.com's design, They have pretty much the same setup except they have 2 extra shims/washers, one on the outside and one on the inside, as seen in (F and G) in this picture:
Having not used either before, I'm curious as to the difference the extra parts make. It's certainly easier for me to build/order the kit-style bulkheads rather than the Kal-style ones with the extra shims, since McMaster-Carr doesn't ship to Canada (or even to a freight forwarder).
Has anyone got any experience with either or both? It seems to me that, installed correctly, either should work well.
