I used liquid flux that came in a squirt bottle. I did pretty much what you described, but on the last few tries I tinned one side of the joint then "tack" soldered the fitting on. I kept heating and squirted it with flux and the joint flowed with no extra solder being added. It worked really well on my RIMS vessel.

Safety Question:

I noticed at the begining of this thread BargainFittings said he needed to get a new insert for his respirator rated for this type of soldering.

I'm reading a few different types of flux and solder now being used. What safety gear are people using? I have a normal respirator from Lowes with the disk like inserts on both sides.

I just want to make sure before I dive in, which I certainly will thanks to everyone on this thread, I'm not killing the few and weak brain cells I have left.

Thanks

I just did mine outside on the porch with my back to the wind. Hopefully that was ok

I used a similar respirator, worked outside, and used a fan.

Read the MSDS and draw your own conclusion, but it didn't worry me enough to seek out more extravagant PPE.

Wear safety glasses and closed toe shoes at a minimum. I do my work outside, and if there is no breeze I will use a small fan. Should be fine.

Did mine outside. Note that most particulate filters don't offer protection against mists and vapors. If it says P100 it isn't doing any good for the vapors.

yeah, they DO make a big deal of eye exposure in the warning label/MSDS. It is hydrochloric acid, after all, and you are boiling/vaporizing it...

Very interesting stuff. Any suggestions on whether (and how) this could be done effectively with a 1/2 inch coupling, with nothing protruding into the interior, for a bottom, dead-center kettle drain? I'm wondering whether the vertical configuration and the weight of the plumbing fittings would push the limits of the solder strength, and whether I would be better off with a weld.

I do not weld, but I suspect that I could solder effectively as long as I were not graded on beauty.

The weight won't be a problem, but the danger might be having a long pipe extending downwards that could torque the connection when you open and close the valve.

I say... try it. You'll turn the keg upside down when you work on it, so that makes it easy to add extra solder. Keep the drain as short as possible, or support it from below.

Test before filling with hot wort. : ) Let us know how it goes!
