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 ### ⭐⭐⭐⭐⭐ The best invention for fixing wires that mankind has ever made. *by W***4 on 2 August 2021* ### ⭐⭐⭐⭐⭐ Good quality *by J***D on 27 March 2025* ### ⭐⭐⭐⭐⭐ easy to use and works as described *by K***R on 14 November 2025* ## Frequently Bought Together - 120PCS Solder Seal Wire Connectors - Sopoby Heat Shrink Waterproof Butt Connector Kit Insulated Automotive Marine Electrical Wire Terminals - SEEKONE Mini Heat Gun, 350W 2-Temp Settings 500℉ & 842℉（260℃& 450℃） Fast Heat Hot Air Gun Tool with Reflector Nozzle and 4.9Ft Long Cable Overload Protection for Crafting, Vinyl Wrap and Shrink Tubing - Ginsco 580 pcs 2:1 Heat Shrink Tubing Kit 6 Colors 11 Sizes Assorted Sleeving Tube Wrap Cable Wire Kit for DIY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/346642993-120pcs-solder-seal-wire-connectors-sopoby-heat-shrink-solder-connectors](https://www.desertcart.hr/products/346642993-120pcs-solder-seal-wire-connectors-sopoby-heat-shrink-solder-connectors) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-16*
