XUUAP only use high quality copper, solder, and adhesive lined tubing to craft our wire connectors which could be widely used in automotive, marine and home project applications. Easy to Use Strip the wire away from the insulation and insert the Connector. Apply heat while rotating the connector. Heat-Shrinkable Shrinkage ratio 2:1. Polyolefin heat shrink butt connectors improve Pullout Strength. Insulated & Water Resistant Hot-melt adhesive provides excellent waterproof property. Melted solder ensures wires Strongly Connected. Wide Applications: home improvement Vehicles: cars, trucks, golf carts, trailers motorcycle, boat, DIY electrical wirings and other outdoor applications. Solder Seal Heat Shrink Wire Connectors Easy to Use - Makes butt connections a breeze. Electrical work gets cut in half! You need a good wire stripping tool, and a reliable heat gun or lighter for melting the solder and shrinking the tubing. Basically, with one step you get a soldered, sealed, and insulated connection. It does take a bit of practice but once you get the hang of it, it's pretty neat. Technical Specifications Shrinkage ratio 2:1. Material: Polyolefin Tubing with Solder and hot melt adhesive Inside. Minimum temperature for solder to melt: 280°F / 138°C The temperature of the solder completely melted: 320°F / 160°C Minimum shrink temperature: 176°F / 80°C Operating temperature :-67°F / -55℃ - 257°F / 125℃ Note For best result, please use a hot air gun and rotate the connector to evenly apply heat. Please raise the temperature from low to high gradually when you use the hot air gun to heat the wire connector. Please DO NOT set the high temperature at the beginning, or the surface of connector will be over-heated, which will lead to the tube melt while the solder ring still not melt. Keep the hot air gun at the proper distance. Don't get too close. ## Features - ✅ ONE-STEP WATERPROOF & INSULATED CONNECTIONS | FAST & SECURE: Stop fumbling with crimping tools and soldering irons. Our all-in-one solder seal connectors provide a truly solderless experience, creating a rock-solid, fully insulated, and IP67 waterproof seal in seconds with just a heat gun. Get professional, factory-grade splices without the hassle. - ✅ PRO-GRADE RELIABILITY FOR HARSH ENVIRONMENTS: Engineered for the demands of automotive and marine use, our connectors feature thick polyolefin tubing and a hot-melt adhesive lining. This dual-wall design provides superior pullout strength and resists vibration, abrasion, and moisture—perfect for engine bays, bilge pumps, and exposed trailer wiring. - ✅ ACHIEVE THE PERFECT SOLDER FLOW | PRO TIP: For a flawless connection every time, use a heat gun and keep it moving. The low-temperature solder is designed to melt and flow *after* the tubing shrinks, creating a powerful bond. (Using a lighter can damage the tubing before the solder melts). This simple technique ensures a perfect, conductive seal. - ✅ THE IDEAL GAUGE FOR COUNTLESS PROJECTS: This 100-piece pack is dedicated to the RED 22-18 AWG size—the most common gauge for automotive accessory wiring, LED lighting, stereo systems, low voltage landscape lighting and DIY electronics projects.
