We love cool items and cool lifestyles. Our goal is to keep developing cool projects, so that we can offer numerous cool products and bring cool lives to our customers continuously. Started in 2017, we launched our first wire connector kit and we have specialized in it for over years. During this time, our cool products have helped a lot of people with their cool work. Now, we have launched amounts of connector kits to meet different needs. Started in 2017, to help our customers do their work well, we exclusively launched wire connector kits as our first product. It’s a very good beginning and it gives us huge courage to keep working on cool projects like this, so that we can bring more cool experiences to our customers. 1. Our products are created to make our customers’ cool projects come to life. Our products can fulfill the most needs for wire connection. 2. We take the quality of our products seriously and they are compliant with IS0 9001:2008, ROHS, SGS and CE standard. Solder seal wire connectors come with IP67 water-resistant rating. After being heated, they shrink and water will not be able to go inside, preventing any short circuit issues. Widely used on boat, vehicle, motorcycle, home, factory or marine. Our wire connectors are upgraded to use exclusive material in the butt connectors to avoid shrink tubing melting before solder ring. The success rate of connecting wire has been greatly improved. Polyolefin Tubing Outside and Hot melt Adhesive Inside make connection strong and waterproof. Note: We suggest the temperature that the hot air gun should set about:400-600℃ (752-1112°F) 200pcs Wire Connectors Heat Shrink Connectors Butt Connectors 40pc Wire Connectors Lever Wire Connectors Kit

    • AMAZING LITTLE TOOLS
Number of Items: 120
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.

    • Fast and safe way to connect two electrical wires
Number of Items: 120
I purchased the Kuject Heat Shrink Solder Seal Wire Connectors and used these types of connectors for the first time ....and I really liked it! I connected 8 wires using 4 of these red connectors and they worked very well. One end of the connector is a little larger than the other end, which allows you to use two different wire sizes. I used just a plain heat gun (I use it for stripping paint and other uses), inserted the two bare wires, and heated the connector. The connector insulation "shrinks" pretty fast against the wire's insulation to make the connection as waterproof as you can probably get. The only issue I had was, it takes longer for the solder to melt than it does for the connector insulation, and it is difficult to tell when the solder has melted. After 4 connectors, I could look close and see the melted solder moving along the copper wires and that was the way I could determine the solder had melted. One connection I overheated and the connector insulation almost melted into. You have to watch close to see when the solder has melted or melted into the connected wires. Heating the solder by rotating the wire simultaneously, seems to help melt the solder quicker. Other than it being a difficult to tell when the solder had melted inside the connector, this is a really good way to connect two wires with solder, and insulating them. I will buy more of these and become more proficient at using these connectors over time. ... show more

    • They do hold well
Number of Items: 120
These do work. At first it seemed like the solder was not flowing properly and I was heating a long time with one of the cheap portable heat guns but I didn’t realize that in reality it is not the flow that does the trick with these. If you wrap your wire correctly and insert into the connector, the solder basically makes a nice clamp. The solder doesn’t really flow as much as grip your wires and that is fine for me. It sets up well and holds strong after just a few seconds. It took me a few tries before I realized how they work. It says that the ring may not fully flow and it does not but it does deform into a vice like grip and I’m fine with that as the copper is what I’m connecting, not the solder. Once you get past that it is a lot easier to accept. Now if my heat gun is sub par I understand that it doesn’t ad to the flow characteristics but it did exactly the same thing with a lighter so it works how it works. They do hold very strong and I actually prefer just the clamp ring for car audio. Much better than crimp connections and seals apparently water tight with the adhesive included. I was not able to burn the plastic with the lighter either so that is a plus. Overall once past the learning curve this is a fine product that I will continue to use. ... show more

    • Quick, Clean, and Solid Connections Every Time”
Number of Items: 120
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. ... show more

    • Saved me from a $1600 car repair!
Number of Items: 120
Review Image by Lyubomir N. Kolev II
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. ... show more

    • Solder flowing issue
Number of Items: 120
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 ... show more
