Review: They work great--but are a bit tricky - 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 desertcart.) 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... ## Features - PREMIUM SOLDER SEAL RING: Tubing reduces in size, the enough solder will melt and flow through the stripped wires, ensure a long lasting connection for your application - BETTER WATERPROOF SOLUTIONS: Double wall design, Hot Melt Adhesive inside ensures wires strongly connected and prevent wires slipping from the terminal; Polyolefin outside tubing provides insulation and improves pullout strength - ABRASION RESISTANCE HEAT SHRINKABLE TUBE: Premium tube materials are specially designed to be used in harsh environments.

Two of the wires end up being twisted together and inserted into one side and the third wire ends up on the other side. You’ll likely have to use the next size up to accommodate the double strand. I’d recommend adding heat shrink to the side with the single wire, as it may not seal as well as the other side, since it’s stepped up. The connections I made this way have been in service on my car for more than two years without any issue. **Q: Do these connectors work on 14 awg solid copper wire (in 14/2 waterproof cable) laid underwater to a small island (110 vac)?** A: Hi friend, we are so sorry to tell you that these solder connectors are not suitable for solid copper wire. Actually they are designed for stranded wire. We recommend you to use heat shrink crimp butt connectors. It woule be safer for your projects after the solid copper wire being crimped and heat shrinking. If you have any additional questions, just contact us seller. We will do our best to assist you. Thank you! **Q: Can this be used with AC electrical?** A: It can be used with any wire. You have to find the size that you need. My husband used it on a beacon light that goes on top of your vehicle and it works really good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product! *by R***A on November 4, 2024* I have used several of these connectors for different projects, including adding accessories to my RZR and fixing various appliances around the house.
