Sweat - Thread - Sweat 1/2" tee

Because I can't solder three copper joints at once, I had the idea to get a tee that was two sweat joints and a threaded joint. The hope was that I could order it off of Amazon for delivery, or if I was lucky, find it in a local store. As it turns out, one local Lowes did have what I was looking for.

I learned that the terminology for this type of part is CxCxF:

I learned that the Nibco part number for the part was 712, LF is needed in the part number for low lead if it's being used for potable water, and -12 sometimes designates a 1/2 inch part

Here's a google search on the part number that wasn't terribly helpful:

Based on the part number, it turns out that Lowes has it, but it's misfiled as a 1-1/2" part. Inspection of the listing seems to show that it's really a 1/2" part, even though the picture oddly shows a 3/4" part

Here's a Mueller part with a different part number:
