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 Heat Shrink Solder Seal Wire Connectors Kit 120PCS, Waterproof Butt Connector Heat Shrink Electrical Terminals, Insulated Solderless Wiring Splice Connectors for Marine 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.hr/products/149432174-waterproof-heat-shrink-solder-seal-wire-connectors-120pcs](https://www.desertcart.hr/products/149432174-waterproof-heat-shrink-solder-seal-wire-connectors-120pcs) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-15*
