Kuject Heat Shrink Solder Seal Wire Connectors Kit 200PCS

Wiring made easy, I’ve had these for about a year now and I use them ALL THE TIME. They melt down easy with a lighter, they are very strong, cheap to by, they keep the wires stable, and the material doesn’t catch on fire after high heat. Very satisfied. I will be buying more when I run out.

Picked these up for wiring on my builds and they work great. Super easy to use—just strip, insert, and heat. The solder flows nicely and the heat shrink seals everything up tight, giving a clean, solid connection without needing separate tools. I’ve used them on automotive wiring and they hold up well, especially with the waterproof seal. Way quicker than traditional soldering and more reliable than basic crimp connectors when you want something sealed and durable. Nice assortment of sizes and the case keeps everything organized. I do a lot of my own wiring and tuning work, and these have definitely made things faster and cleaner.

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

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.

Convenient to use.

I do a lot of 12 volt electrical wiring. I believe this is probably the best way to join two wires. Just simply push each wire through the ends making the copper strands intertwine together. Then, heat the solder which makes a permanent bond. This will also shrink the tubing, giving you a tight waterproof seal that also holds the connection even better. I plan to use these from now on. Also, very good price for this kit that contains a variety of sizes.

So, I actually ordered these by accident, but after I realized my mistake, I figured I would give them a try. I thought I bought crimp and seal connectors like I always use, but these are a low temp solder that melts with a standard heat gun. I used them last night on a replacement headlight connector in a Silverado and they worked like a charm. Cut the old connector off, installed the solder connection and the new pigtail, mate wires and slide the connector and hit it with a heat gun until the solder melts. EASY. I had my doubts at first because I figured the connector would melt before the solder made a real connection, but they worked like a charm. The connector shrunk nicely around the wire and the colored sealant melted into place and spread out and shortly after, the solder flowed into the wires. pretty slick to be honest. the joint set up and seems to be watertight and a solid connection. good value and I'll be using these more often for sure. They seem to be well made and look like the connection will hold up.

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
