Solder Seal Wire Connectors 300 Pcs - Heat Shrink Connectors, Solderstick Waterproof Solder Wire Connector Kit, Electrical Connectors, Automotive Solder Stick Connectors

I have been soldering for a while but would still call myself an amature, when I found out about these however I grabbed a box and gave it a go.They are significantly easier to work use and all you need is a heat source (heat gun or lighter) and your sorted. I do still use a soldering iron from time to time however as these aren't sutable for every situation but they are very useful when you can use them!

Was slightly unsure about how well these might work - but they do the job well. thin electric wires to outdoor ornament were sliced by shears and mended simply using these. A myriad of sizes available too. You'll need a decent heat gun to make them seal properly though.

I bought a box of similar a while back and when these came up I grabbed them as well because they are very good for in line joining of multi-strand cable. The electrical connection when soldered and done properly should be better than any mechanical means because you keep the surface area of the cable intact.To use find the right size for the two cables, push them together so that the solder ring is over both ends and then using a hot air gun heat until the solder melts. The only tricky bit is to not overdo it and over heat the plastic sheath which does shrink down over the join like heat shrink. Try and do it quickly seems to work best. I also make sure I've got additional heat shrink to go over the joint when the soldering is done. That way I know I'm properly insulated.A huge box of sizes that should last a long, long time.

Easy to use

Great work very well , good selection of fitting ,only one thing pitty they didn’t do a bigger amount in one box as k use them a lot10/10. Always good to have them in your workshop

Well try and hold the little part in place and heta it without burning your fingers is a joke if you were working on a workbench on a flat surface might be ok but to use in the field so to speak total rubbish

The top connection (blue, in the photo) shows how poorly the joint can be; the solder hasn't really flowed into the wires at all, and frankly, I'm not surprised.The lower joint (yellow/black) is better because I added a small amount of soldering flux to the joint before crimping it; this enabled the solder to flow much more easily and made a reasonable connection.To be frank, the wires need soldering together BEFORE being crimped and then resoldered whilst heating up with the heat/hot air gun - then the joint is well made but then again a piece of heatshrink would work as well.A great idea if it worked better for users without access to flux and soldering equipment.
