"Wow!!! These are such a great idea! I came across these at my place of work watching a technician repair some broken wiring on a trailer, so I bought some myself to repair a wiring loom in the door of my partner's Audi A3. So easy and straightforward to use and you get a solid connection! Never again will I use a crimp connector ⭐⭐⭐⭐⭐"

  • FAST AND SIMPLE PROCESS - One-Step solder and seal process for all your connections.
  • WATERPROOF - The insulation tubing has a unique dual-walled design; polyolefin tubing on the outside and hot melt adhesive inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation. Dual walled tubing ensures a waterproof seal and prevents wire corrosion.
  • EASY IDENTIFICATION - Color-coded tubing makes it easy to identify the right size connector for every application. Measure your wire, and easily choose the right connector by looking at the wire size chart on the box.
  • COMPLIANT WITH ALL RELEVANT STANDARDS - Our heat shrink connectors are compliant with ROHS, ISO 9001:2015, SGS and CE standards.
  • SolderSeal™ BRAND QUALITY COMMITMENT - We stand behind the quality of our products. If for any reason you are not satisfied with your purchase, please contact us. We will work on every inquiry to ensure your satisfaction.

• Strip wire insulation 1/3 of an inch on both wire ends

• Choose the right connector size for your wires




• Position the wires into the solder butt connector

• Use a heat gun at a low setting while continuously rotating the connector

• Pro tip: heat gun deflector nozzle helps to distribute heat more evenly




• Connector tubing will shrink down, and solder will melt and flow through the stripped wires

• Allow your terminal to cool down

• Your waterproof connection is now complete




Could I use a small butane or propane torch instead of a heat gun?

Definitely! Just don't get it too close as you will over melt the shielding

Are these connections weatherproof?

Yes, remember to heat both ends of the sleeve and they will seal watertight.

What is a Wire Connector?

Wire connectors are used to fasten two electrical wires together. The connector protects the live wire from exposed surfaces and metals. The wire connectors prevent dangerous short circuits and faults. Not to mention, wire connectors come in a lot of colors, materials, and sizes. If you are a DIY person, you must consider getting wire connectors for your project. However, while fastening wires in a wire connector; make sure that the electricity is turned off.

Are Wire Connectors Safe?

Yes, wire connectors are safe. They serve as a protective layer and save the wires from overheating. Moreover, when a wire goes to a connector; the connector shrinks and fastens two wires together; which prevents the loss of the wires connection.
