BargainFittings - do the new weldless kits come with the solderered washer/nut combo? Is it standard or must it be requested?

Earlier in this thread Wayne mentioned the heat sink of the water in the kettle being enough to keep the solder from Melting in the fitting. I just want to make sure because I want to put a swaged fitting in the bottom of my BK with direct fired flame right under that soldered fitting. If that will hold , then Im gonna do it..

as long as you don't dry fire the keggle and have water in it when its on heat you will be fine

The surface that contacts the liquid will never get above 212F, but the further the metal sticks out into the flame, the hotter it will be. The propane is burning at a few thousand degrees, so even if it sticks out an inch, you have the potential for disaster. I assume you'll have to attach some sort of plumbing to this fixture which will extend further into the flame. That plumbing will most certainly see extreme temperatures.

My advice: go electric

Don't put fire on the fittings and you will be fine, Flame on them and you will probably have solder in your wort and a big mess on the ground, burner, etc.

I ran mine for the first time this weekend and had zero issues with any of the 6 fittings on my HLT.

+1. Soldered fittings should only be used for electric rigs. You don't want to risk failure from the flames hitting the bottom or licking up the sides. 400F-600F is the melting point of most solder...you don't have to see the flames touching for it to get that hot.

Again, for anyone struggling with soft solder, just get a bottle of mapp (yellow bottle) and you can braze with 54% silver solder just fine. The flux is a lot easier to work with than the liquid harris stay clean.

my first attempt was with yellow MAPP gas, and Silver Baizing flux, but I didn't have braising solder, lets say it was not successful until I got the liquid flux

The price of 56% silver solder alone is a turnoff. I wanted to braze my fittings, but have found the lead free plumbing solder to be plenty strong when using a keg tool. Plus, all that stuff can be used for other projects....I personally won't do a whole lot of brazing anywhere else.
