Does it need to be used with other tools?** A: Yes, you need to purchase preferably a heat gun. The heat gun is used to mould the connector around the 2 broken wires securely so that they connect as 1. **Q: What’s it up rating?** A: I find these very useful indeed. They give a prefect connection, which is waterproof. (Although I always use heat shrink tubing over the connections to make certain they are totally sturdy and waterproof.) **Q: is this suitable to reconnect a cut off hedge cutter cable (240v 5a). Also I just have a wind proof lighter is that ok and will the flame not burn it?** A: Good for fixing wires together. I just use enough hat air till the solder melts and plastic tightens. Gentle heat. I use a heat gun that straps paint. ## Frequently Bought Together - Kuject 50PCS Solder Seal Wire Connectors, Waterproof Heat Shrink Butt Connector Solder Sleeve Self-Solder Insulated Electrical Butt Splice Wire Terminals for Marine Automotive Boat Truck Wire Joint - ASHINER Heat Shrink Tubing Kit - 580Pcs EVA Material in 6 Colors and 11 Sizes - Ideal for Electrical Insulation, Repairs, and Wire Connectors with User-Friendly Design and Storage Case - SEEKONE Mini Heat Gun 2 Temperature 260℃/450℃, 350W Handheld Hot Air Gun Tool 1.5S Fast Heating with Overload Protection, Non-Slip Rubber Body, Nozzle for Craft Embossing, Shrink Wrapping --- ## 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/220199238-kuject-50pcs-solder-seal-wire-connectors-waterproof-heat-shrink-butt](https://www.desertcart.vu/products/220199238-kuject-50pcs-solder-seal-wire-connectors-waterproof-heat-shrink-butt) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
