Kuject Heat Shrink Solder Seal Wire Connectors Kit 270PCS

These are freaking great! Easy to use and seal nicely. Will buy more intime for sure. Used them for fog light wireing on my cars and also on a cctv camera, worked great even through a storm with 90 mph winds and heavy rains.

TL;DR - the auto shop wanted $1600 for parts and labor. Between these, some parts, and a heat gun, my car runs better than it has in a couple years. Backstory: I have a 2013 Hyundai Veloster Turbo and the last couple of years coils and spark plugs have been going pretty fast. I figured it was something with the ignition wiring or something else electric. The shop I've used regularly quoted me $1600 for new spark plugs, coils, and a wiring harness (all they would use were coils direct from Hyundai for $970!) plus labor. For a 12 year old car that's worth less than $3k I said no way, especially giving Hyundai that much for parts. I bought these guys, a set of coils and spark plugs from Amazon, a heat gun, wire cutter, and electrical cloth tape for about $70. With the heat gun, they worked great. The solder doesn't melt quite how you'd expect, but it does turn into a softer blob and may leak slightly silver - takes a minute or two after you focus the heat there with a narrow nozzle. Make sure the wires are good and jammed or twisted in the middle of the sleeve! I made the mistake initially of not having them touching too well before using the connector and had to redo - luckily they come off fairly easily with heat and wire stripper if needed. All in all, very pleased and having zero issues so far! They shrunk well, connections are solid, and I know the wires will be better protected from humidity and heat.

I tried out on a couple projects I had and they performed well. great price and the heat shrink works well too.

Very effective and seals very tight using a heat gun. The solder melts quickly though I did pre solder the wires prior to sealing.

Great for wiring and reconnecting broken wires. Use heat gun or blow dryer.

I’m really impressed with this Kuject wire connector kit. Having 120 connectors covering multiple wire sizes makes it a very useful kit to keep around for automotive, marine, and general electrical projects. The best feature is how simple the connections are to make. You insert the wires, apply heat, and the connector solders and seals the connection without having to juggle a soldering iron, solder, and heat shrink separately. I especially like the waterproof heat-shrink design. Once properly heated, the connection feels secure and protected, which gives me extra confidence when using them in areas that may be exposed to moisture. The different sizes are easy to identify, and everything comes together in one convenient kit. It makes wiring repairs cleaner, faster, and much less frustrating. Five stars!

Great for quick repairs. Super easy to use.

Wire shrink works good but this solder refuses to melt. End up catching the clear tubing on fire before it'll actually start to flow. I've tried multiple torches lighters different settings different distances. Same issue. Gave 3 stars because at least the heat shrink is super good and holds the two connected wires together. I've TUGGED on the heat shrink and it continues to hold. If nothing else it's good for that

Hat mir über 900€ gespart, für ein Ersatzteil. Der Umgang ist wirklich unkompliziert, kann ich sehr empfehlen. Wenn man lange genug mit 400°C drauf hält, zerläuft es auch wunderbar!

value for money

Bonne qualité

Sono di ottima qualità possono essere utilizzati anche con un accendino (non a cannello), basta averci "la mano", andarci leggero, per non distruggere la guaina.

Si saldano anche con un phon asciugacapelli. Ottimi
