  • Great value for a bulk pack of solder heat shrink connectors!
Color: Red
Update: I had to remove a connector and the heat shrink was in fact tight and could not be slid off. Original review below. These do have a more milky clear than others but they work. They are a great value after all! The price of this bulk package is quite appealing if you have hundreds of wires to solder and heat shrink. Once you use them the value is not there. These solder connectors use a harder heat shrink than some of the other connectors I have used. They also turn milky white when they cool and some seemed to slightly expand upon cooling. This causes the colored ends to not grip the wire and it makes soldering the ring a little bit of a challenge. Also the solder rings in the connectors do not flow as well as some of the smaller packs I purchased. There was not any instructions on the packaging with regard to what temperature to use on these. I searched the web and found a NTE (name brand connectors) tutorial video. They heated the ends some on each side and then came back to melt the solder. I believe this was to get the ends to bite down on the wires so that things wouldn't move around when you go to melt the solder ring. Their product page also said the solder flows at 140C. I set my heat gun to 200C and got to work. Surprisingly I did not ruin any connectors along the way. For some reason sometimes when you are first starting to heat the connector they almost jump to the side on you. I dont know if the plastic gets slick or the heat in the wires makes them wormy but the biggest hurdle in the process is getting the two red ends sucked down to the wire. At one point I was fighting a wire that was noodling around on me and i thought my wire actually poked through the heatshrink. I put down the heat gun and checked it and it had not. I adjusted the wires and applied some heat and called it done. The best part of this type of connectors is the fact that you can solder without smelling lead or flux. You still get the smell of polyolefin (heat shrink) but that is nothing compared to the smell of lead and flux to me. There are also no clouds of toxic smoke to avoid during the process. I cant say whether or not the resistance across this is as good as what you would get with some old school leaded solder and that smokey cloud it provides but for a quick and clean solution this type of connector is the way to go. I did continue to apply heat for a few seconds after all solder had flowed in an attempt to avoid cold joints. I have no idea if this worked or not since I have not measure the resistance yet. In the end I unfortunately could not get the ends of these connectors to consistently grip the wires I was using so this product is just okay to me (3 stars). Other products provided a significantly better grip and solder flow for a slightly higher price per connector. I do not think these would provide a water tight seal at least for my application. ... show more

  • Handy
Color: White
I have a primary so, a soldering pencil was banned by my doctor. I car hold a lit match with my non-dominant hand so, I can join two wires.

  • No more Short in headlights
Color: Purple
For too long I put up with headlights that would intermittently shut off while driving at night! Usually just one.... or the other.... but a couple times both! I replaced the sockets for the headlights, but it did not solve the issues. Even stranger was that if I popped the hood and touched the back of the headlight, it would turn on and stay on for the rest of the trip. (usually). I finally got fed up and replaced the connection of twisted together wires covered in electrical tape with these connectors. They were easy to install with a heat gun, and I have not had the issue again since I installed, about 3 months ago. ... show more

  • Great connectors
Color: Red
Used these to splice longer wires into pre-terminated servo cables. Use a heat gun for best results. 200c/400f and glue/heat shrink secures wires then melt the solder ring in the middle. Makes a strong connection quickly. Worked well on 22-23awg stranded wires. Servos are used for model railroad turnouts. ... show more

  • Makes life so much easier
Color: Red
They work as advertised and make life so MUCH easier. The trick is to get the right amount of heat. Too little heat does not melt the solder. Too much heat and I had one or two get a pin-hole burst when the solder melted. But that was an exception to the rule. I usually heat the ends first so the rings shrink and grip the wires and then I do a few slow passes over the middle and you will see the solder melt and flow. Takes about 10 seconds or so to solidify. This saved so much time vs. crimping, connecting wires, and adding heat shrink on top. ... show more

  • Can't get any easier
Color: Red
I love using these things and I use them very often for when I am connecting wiring for custom headlights. They are so convenient and I haven't had any issues with a bad connection as long as you heat it up enough to melt the solder.
