Good product!
Size: 120PCS
I have used several of these connectors for different projects, including adding accessories to my RZR and fixing various appliances around the house. One of the standout features of this kit is its ease of use. The solder seal connectors create a strong, waterproof bond without the need for complicated crimping tools, making my work faster and more efficient. These connectors provide a secure connection that holds up well, even in tough conditions. I was particularly impressed with how well they performed when used on my RZR, where they faced exposure to vibrations, dirt, and moisture—yet the connections remained intact and reliable. For appliance repairs, the heat shrink design ensures a tight, insulated seal that has given me peace of mind knowing that the electrical work is protected. Overall, this kit has proven to be an invaluable addition to my toolkit. Whether for automotive, marine, or household electrical projects, these connectors have consistently delivered quality results. If you need dependable, high-quality wire terminals that are waterproof and easy to use, I highly recommend giving this product a try.

They work great--but are a bit tricky
Size: 120PCS
I bought these because I do a lot of guitar electronics, and I was just getting tired of soldering wires together, then applying shrink tubing. These things are great; but you have to know a few things. First, don't expect that the solder inside will melt as quickly as you see in the ads. It melts, but it takes a while. Remember to heat all around the diameter of the connector, not just one side, for a more even distribution of solder, and better shrinking of the tube. Second, make sure that the ends of your wires are both long enough to reach to the center of the connector. just slide the two ends past each other, then apply heat. Not only does the solder melt to solder the two wires together, but the body of the connector acts like shrink tubing, and the two rings at either end of the connector shrink to help hold the wires in place. Third: heat. It is tempting to use either a butane lighter or soldering iron tip to melt the solder and shrink the tubing, but don't do it. The connector will start to melt (soldering iron) or turn black (butane lighter) The soldering iron can also melt a hole in the connector, which kinda defeats your purpose. A good heat gun is quick, easy, and leaves the connectors looking pristine and perfect. (The heat gun I use is about $20 on Amazon.) A note, though: give time for the finished connector to cool down--like a minute or two--before you test the connection by pulling on it. Also, use the smallest connector that will fit the wires you're using. Using a larger connector may seem easier, but the smallest connector you can use will make perfect connections. I've used so many of these that I'm going to have to order more--only this time, I'm going to get the BIG box...

Worked Great for Me.
Size: 120PCS
I didn't have any problems with these, but I can see how some might. You have to read the instructions. If you just attack them, they may very well melt/burn too much. I used a small butane torch rather than my heat gun. It may not have made a difference, but I felt like I could direct the heat a little better. I'll try the gun another time. I also didn't blast the connector. Rather I took it slow. If you read the instructions, you will see that you DO NOT have to melt the tin ring. The solder is in the ring and will flow before the tin melts. If you wait for the tin to melt, you may very well go to far. However, the tin did melt on several of mine with no issue. The connection was strong. Another observation was the appearance that the clear material had melted through. I thought I had melted a couple because the material was so clear the it looked like to connection was exposed. But when I felt it and looked at it closely, there was still material covering the connection. Nothing was exposed. I've worked on everything from military aircraft to the car radio harness I used these on. I like them and will continue to use them.

Perfect solution to create a permanent fix
Size: 120PCS
I discovered these solder seal connectors a few years back and keep ordering more because I use them for any 12v repair project. I have four on the road trailers including boats, utility and to haul a compact tractor so lighting issues are always coming up. These connectors are a great permanent solution. Highly recommend to avoid.

Quick, clean, and waterproof—solid value for everyday wiring.
Size: 120PCS
I’ve used these Sopoby solder seal connectors across multiple projects—vehicle mods, electronics tweaks, even a few reptile habitat upgrades—and they’ve held up well. The dual-wall design with hot melt adhesive inside gives a strong seal, and the solder ring melts cleanly with a heat gun (skip the lighter unless you like uneven results). Color-coded sleeves make it easy to match wire gauges (AWG 26–10), and the included case keeps everything organized. Once shrunk, the connection is tight, waterproof, and surprisingly durable—even in outdoor or high-humidity setups. Just make sure to heat evenly and rotate the connector for a proper seal. If you want fast, reliable wire joins without crimping tools or messy soldering, this kit delivers. Not fancy, but functional—and that’s what counts.
