Certainly it's a deal breaker if you don't like the idea of soldering or don't have a local source of the cheap silver solder kit.

Why not use a Copper washer? Then you could just sweat the pieces together. Saves on trying to do SS - Copper.

Well, yes, that would work too but then we're not talking about sourcing parts locally anymore. Fastenal shows they have a 3/4" ID washer but it's $13 and out of stock online and in stores. If anyone can find a source for cheap 13/16" ID copper washers, it would be awesome and easy to solder.

Awesome! I am looking into this to use for my chiller. Thought I could mount it inside my kettle. Slowly working my way towards the HERMS. Plus free up some room on my brew cart!

$13 for a copper washer
Could you not fabricate one easily enough from the copper pipe eg;
Cut piece off copper pipe so that it can be banged flat and drilled / shaped appropriately?

I was thinking of using a penny but then I wouldn't of been able to give my 2 cents

Cheers;

Do you really even need the washer on the inside of the kettle? As long as the o-ring you have there can take the temps and can form a tight seal. Why not just use that on the interior. Another option is to have a 1/2" copper bell housing on the interior of the kettle. A brass valve can than screw into it from the outside. The large face on the bell housing provides enough to hold an o-ring in place on the inside. SS washers are used on the outside of the kettle. I know SS will eventually rust if used on the inside, mine did very quickly. I apologize for no pictures i'll post a few as soon as I find the old digi camera.

The oring will definitely just squeeze out without the washer. Bell housing? I'm not familiar with the term outside of the automotive usage. Maybe you mean a female NPT to sweat adapter? Stainless washers will not rust on the inside. The whole keg is stainless.
