TICONN 120 Pcs Solder Seal Wire Connectors, Heat Shrink Butt Connectors, Waterproof and Insulated Electrical Wire Terminals, Butt Splice (120PCS)

These connectors are amazing, as long as you use a heat gun(not a lighter) to shrink them down and melt the solder. I’ve used them for car stereo installs as well as wiring in underglow and interior footwell lights. They hold great and really keep the wires protected from water seeping in and shorting electronics out.

So I’ve been curious about these for a while and finally decided to try them out. My ten year old butane soldering iron finally gave up the ghost so I figured I’d give these a shot before buying a new one. I was super skeptical from all the advertising but I was surprised how well they work. I’m a truck driver and I own my own truck and trailers, all older equipment so I fix a lot of wiring.If you’ve seen the advertisements for these they make it look like you can just slide them on, hit them with a cigarette lighter and be done. They do not work like that at all, however when used properly they work great. You need a good heat gun and you need to hold it on the solder section until you see the solder shrink/flow into the wires. Also the clear heat shrink from what I’ve read seems not to be UV protected so you should run some normal solid color heat shrink over these, I did intentionally leave one exposed on my trailer and I’m curious to see how it does. All that said they seem to create a very strong joint (once they’ve cools down, made that mistake pulling on them while still hot) 100 times better than crimp connectors and it will take time to know if they last just as long as soldered wires but I feel like they will.Will they save you time, maybe if your not well practiced at soldering wires, but honestly I could probably solder two wires in good working conditions just as fast as connecting them with these. Where I think these are going to be the best thing in my tool kit is when I’m in Wyoming, it’s negative 10, dark and windy and all I need to grab is these, some heat shrink, wire strippers and my cordless heat gun. That situation without these I’d probably use a crimp connector as a temp fix and go back later and fix it properly, as far as ease of use these are probably easier than crimp connectors and they’re a solid permanent fix.

Overall this product worked well. The solder material didn’t melt as fast as othr brands I have used which caused the heatshrink material to melt faster and burn quicker than the solder leaving the finished product dark and difficult to determine how well the solder penetrated the wire connection. This resulted in me adding heatshrink over the product the ensure the connection was secure and waterproof.

Love the product. Used them to help my daughter install a new stereo in her car and am confident they won't separate. I like the solder in the middle. All around great design.

This is the best, and easiest way to make a secure and water proof electrical wire connection and or repair. All that is needed, is wire clippers / strippers, and a lighter.1. Slide correct size connector over one side of the wires to be connected.2. Strip about 1/2 inch of ends of both wires of the connection, twisting the bare wire tight.3. Hold a wire in each hand of connection. Bring stripped ends together 90 degrees apart half way on each stripped scection and counter twist the ends together.*Note* Wires should now be in a single run, not side by side.4. Slide connector centered over center of connection. Heat with lighter until solder melts and connector shrinks tightly onto wire.

Great assortment of sizes and easy to recognize colors. Plastic case is perfectly sized.

Easy to use, proper quality. Would definitely recommend using a heat gun, don't try messing with a lighter

They worked for my hooking up my speaker wires but it took a long time under the heat gun. I was getting paranoid as it didn't melt the soder adhesive as easily as in the video. I only removed the heat because I didn't want it to melt the wires.
