Solder Sleeves are the bee's knees!

We just got these solder sleeves in, and they are fantastic. They solder and heat shrink wires together all in one go!

Check out this blog post for the details:


As a professional aviation wire monkey, I can attest to the wonderfulness of this type of solder sleeve. We use an unfathomable amount of them when doing avionics system installations and upgrades. The only real difference I can see between these and the ones that we use, is that ours come with an FAA certification and cost five times as much. :smile:

That’s really cool, I didn’t know these were used in that industry. Someone asked me if these would be good for automotive wiring, I assume so?

The mind-blowing selling point for me was the fact you can make it work with a cigarette lighter, which means you can just throw some in your pocket and work on wire installations anywhere and not have to worry about soldering.

These look fantastic, I can think of all sorts of uses… :smile:

Michael, what size would be appropriate for extending the wiring on the X-Carve ?

They’re great for automotive wiring too. It’s what’s also called an “environmental splice” - those little globs of softer plastic in either end of the shrink tube should form a water-tight seal when properly heated, protecting the solder joint from moisture intrusion and preventing corrosion. They’re brilliant little widgets!

Depends on what size wire you’re using, but if you’re using a gauge similar to the wires already attached to the stepper motor, but the 22-18awg Red ones are probably the best bet.

I was introduced to solder-sleeves in the telecom industry, where they’re used to fix the occasional “oops” on twisted-pair wiring from 19AWG to 26AWG. I gather that a larger version is used for terminating coax shields, largely in aviation, and these seem to often have a drain wire preinstalled as part of the sleeve assembly.

They seem to be available in quite a range of sizes and styles, though they’re such a niche product it’s hard to find a comprehensive list anywhere.

Air Force avionic tech here, we use those for doing shield splices and stuff. But for joining 2 wires together, we use a crimp splice with an environmental sleeve over the top. Solder joins like that can become brittle in a vibration enviroment.
