Fast, Secure Solder Seal Wire Repairs
Simplify your wiring projects with our heat-shrink wire connectors. Designed to deliver a fast and water-resistant seal for everyday wiring fixes without the need for traditional soldering tools.
Engineered for Tough Environments
Built with three integral components that work simultaneously when heated. The solder ring center melts to establish a highly conductive electrical connection, while the dual adhesive seals and heat-shrinkable sleeve contract to prevent moisture penetration.
3 Easy Steps for Secure Connections
Achieve quick, clean, and reliable seals in minutes. Simply strip about 1/3 inch of insulation from both wires, insert them into the connector sleeve to overlap directly under the central solder ring, and apply even heat while rotating until fully sealed.
Visual Quality Comparison
Quality Connection vs. Low Quality
A proper connection shrinks evenly around the wires, leaving a fully sealed and protected joint when heated using a heat gun. Poor quality connections risk uneven melting, deforming, or burning the sleeve, which compromises moisture protection and conductive hold.
What's Included
Choose the Perfect Kit for Your Needs:
We offer 4 different box sizes (50, 100, 250, and 500 Pcs) to suit any project. Each box includes a scientifically proportioned mix of 4 sizes to cover all standard wire gauges:
- 🟡 Yellow (12-10 AWG / 4-6 mm²): For heavy-duty wiring.
- 🔵 Blue (16-14 AWG / 1.5-2.5 mm²): For standard automotive/marine wiring.
- 🔴 Red (22-18 AWG / 0.5-1 mm²): For interior lights and electronics.
- ⚪ White (26-24 AWG / 0.25-0.34 mm²): For micro-wiring and delicate electronics.
(Please refer to the size chart image for the exact quantity of each color in your selected box.)

Frequently Asked Questions
💡 Do I need a crimping tool to use these connectors?
No, these connectors do not require any crimping tools or terminal crimpers. The central solder ring melts to bond the wires, and the tubing shrinks under heat to create a firm, insulated connection.
💡 How much insulation should I strip from each wire?
You should remove about 1/3 inch of insulation from the wire ends and twist the exposed copper strands together tightly before sliding them into the connector sleeve.
💡 What is the function of the colored rings on both ends?
The colored rings consist of hot-melt adhesive. When heated, they melt and flow to block out moisture and protect the electrical connection against environmental factors.
