Solder in it has quite a low melting point so takes a bit longer than you might expect to harden again (give it a minute). I tried bodging 4 wires in one connector and it's still holding them solid. Personally I wouldn't trust it completely to insulate the wires, I think I'd put another heat shrink sleeve over the top because I'm not certain the solder part won't melt through and it'd be difficult to spot. ## Frequently Bought Together - Kuject 400PCS Solder Seal Wire Connectors, 26-8 AWG Self-Solder Heat Shrink Butt Connector Solder Waterproof Insulated Electrical Butt Splice Wire Terminals for Automotive Boat Truck - 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 - Eventronic 400 Pcs Heat Shrink Tubing Kit-3:1 Ratio Adhesive Lined,Marine Grade Shrink Wrap - Industrial Heat-Shrink Tubing - Black --- ## 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.vu/products/369807617-kuject-400pcs-solder-seal-wire-connectors-26-8-awg-self](https://www.desertcart.vu/products/369807617-kuject-400pcs-solder-seal-wire-connectors-26-8-awg-self) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
