Never seen these before but my immediate thought would be applying enough heat to melt the solder would damage the heat shrink.
But another idea may be glue lined heat shrink. As long as its the right size it will be water proof when shrank over a soldered joint.

Lots of people are using them. They solder and glue and join all in one.

I'm a sparky. Just saw an advert never seen them before and wanted some feedback. I always use wagos but these are slimmer and with the heat shrink could be better for automotive

I've used them a bit. The Chinese ones take a little too much heat to melt the solder using a heat gun. You have to watch out that you don't melt and ruin your wire insulation while you're waiting for the solder to melt. After it does, make sure it flows good into the wire strands. When cool pull very hard on each side of the join to make sure you have a good solder connection. It's hard to see if the flow was thorough, so a good tug will verify a good joint. In the beginning I had joints that looked good but the tug revealed that although the solder melted it did not flow into the wires. Also, I use a little flux on the bare wires to try to insure good flow. These are convenient to use, but take some practice to get reliable connections.

Thanks big John. I will give them a whirl. Its finding the right amount of heat that's the key then

Not to be confused with Big John, have a look at this video from Big Clive:

As a means of joining wires, this sort of thing work well, but where these type of connectors, along with wire termination crimps 'fail' in my books is if the insulating sleeve is a hard type. With these, over time, while the connector itself doesn't usually fail, the wire's insulation adjacent to it does. They need to have a soft, flexible insulation.

was just going to link that one myself! There are some good crimp ones with the heat shrink and glue ring in them too, ive used those quite a bit on my rally car. I dont know if i would get as consistent results with the solder ones.

We use these at work and are great for aircraft and in an Apache/Lynx/Gazelle are subject to 10 times more vibration and heat that a mini could ever put out. The trick is to use one or 2 as testers on some spare cable to get your heat settings set up. And I would only use an adjustable heat gun!

They work fairly well but you do need to do a test or two. A hot air gun is a must, a blow torch is a no-no.

i hope you meant you're using something similar at work, not the actual ones in the link  :lol:

Haha very similar, but no not the same! I think the official name for them are ‘solder sleeves’ and they’re very useful for tight spaces where crimping tools won’t reach. Perfect for a mini!

Yeah, the mil-spec ones are better for sure. My guess is the band is made of real tin lead solder, whereas the Chinese ones contain lead-free.
