Water-proof solder wire connectors?

Anyone have any experience with these? Just insert wires and heat....

Just don't use them down south without A/C on all the time.

I saw them somewhere before and did worry about something with solder that melts at that low of a temperature.

The mechanical joint is provided by just the heat-shrink tubing and that solder. I wouldn't want that unless the wire is well-supported on each side of the joint... which is rarely the case in real installations.

Not that low - 138 to 170C depending on the tin-bismuth alloy mix. It's been used for decades as an alternative to tin-lead in electronics manufacturing in the computer worlds for circuit boards, wire harnessing, etc. I'd be more concerned with getting enough wire volume that the solder would actually form a good mechanical bond.

I use conventional lead-tin rosin core solder (hate lead-free on electrical stuff), then marine shrink wrap... or if I don't have marine shrink handy, I'll use 'liquid electrical tape' and put regular shrinkwrap over it before the liquid goo cures, heat shrink it, and wait for the goo to cure.

Yup, no substitute for the good old Western Union splice and heat shrink.

I have mixed feelings about it. On one hand, personally, I think that it's a bit mickey mouse when it's just as easy to do a connection with better mechanical strength and and more surface in contact. On the other hand I'm always in favor of anything that gets someone who doesn't have much shop experience to try and do something for themselves rather than have to rely on others. So if it does that, I'm in favor of it.
