Sopoby'S Waterproof Solder Connectors - Complete 140PCS Kit For Marine, Automotive And Home Wiring Review

I was skeptical about these but so far I'm impressed with how easy they are to apply. Only time will tell how they do in the long run. One bit of advice is to use a heat gun instead of an open flame. The shrink tube can melt quickly if you expose it to flame too long. I got much better results using the heat gun that a lighter or torch. But yeah, I'll buy these again - soon.

I've tried a heat gun, a soldering iron (pulling that out kind of defeats the purpose of these things) and a lighter. I too find it next to impossible to get the solder to melt before the tube itself is destroyed. I thought this would be an easier alternative to soldering and using shrink tubing. It is not. It takes longer and the end result is iffy at best. The tube shrank, but did the solder melt? I can't tell. I pull the wires and they come apart. I have to strip and try again. Yea! The…

I really like these self soldering heat shrink connectors. I have used them for various wiring projects on my F250 pickup, from installing light bars to installing a new sound system. They have worked for me every time. First I slipped the connector over one of the wires. Then I wove the wire ends together and slipped the connector over the wire ends so that the metal ring in the center of the connector was centered over the wire splice. I then heated the connector with a heat gun, moving it…

As an Engineer I found this to be a great idea so I tested it out on a piece of wire which I stripped and twisted together. I slid one of the red shrink sleeves over the joint then used a lighter, and after a few seconds of moving the flame back and forth, the solder seemed to melt and it looked to be a good connection. Then I tried pulling it apart and the connection failed.I then tried again, but this time I dipped the stripped ends of the wire in Flux which is a very necessary part of the…

It was my first time using these and overall they're a great product. The included sizes worked great for my car audio application where I was connecting 2-3 22-18ga wires.I used my Wagner heat gun to shrink and solder, which worked well overall. There was a bit of a learning curve, some tips or instructions would have been welcome. The biggest issue I had was the solder would take long enough to melt that the heat shrink would start to melt thru a bit exposing some of the wire connection. Not…

I'm not really sure about the water resistance since my uses so far haven't really tested that aspect. But, having these around makes small wire repair quicker, somewhat easier, much more compact, and probably a just as water resistant than other methods such as wire nuts and Plasti Dip and probably a lot more water resistant than a "Western Union pigtail" and electrical tape. It does take some practice to get good at applying the heat with a heat gun to liquify the solder without over-melting…

I bought this for my stereo system install. WOW. This really works great. In fact so good that I bought another kit. Thanks for attention!

Used product to wire thin 24 gauge led wire to a 16 guage lead. The connection was very strong after I let the connector cool. Use a good heat gun and take your time. You will see the metal mix with the wires for a good connection.

I've used this type of solder heat shrink connector (different brand) in the past and they were not this difficult.These are very finicky to use. Easy to split the shrink wrap before the solder melts. I started out trying to use my heat gun (1800w adjustable). But could not get the solder to melt enough to actual hold the wires together. Moved on to the trusty torch. This is where patience and using something else besides your have to hold the wire. I found that if I hold heat far enough away…

I have 12 volt recessed lighting in basement; dozens of corroded ceramic sockets. Changing the bulbs and cleaning were no help (MR16's with straight pins). I bought replacement sockets and because of the low voltage and dampness, I was planning to solder all these, on a ladder, with very short pigtails in the ceiling fixture (can). I bought these connectors as I wanted solder and heat shrink. My first connection I tried a flame (butane) but that was too much heat. I switched to hot air gun, and

I was skeptical at first but I thought what the hell I'll give him a try. I needed to rewire a engine wiring harness. I thought that these may save me some time and they definitely did. HERE'S MY 2 CENTS. Slide one of the wires in half way, the heat that end so the heat shrink tube closes but make sure you don't active the solder. Now that end and wire is held in place. All you need to do is put in the other wire and finish. Super easy.

Based on all the good reviews, I went out on a limb, and tried something new; and I'm glad I did. I replaced an old lightbulb fixture with an led panel, and used these heat shrink connectors to connect the jumpers to the ballasts wiring, and to the home wiring, and everything worked on the first try! Because the heat shrink connectors are clear, you can see that the exposed ends of both wires are crossing inside the solder ring, and then you heat it up and you can see the solder contract into…
