Heat-Activated Wire Repair
Seal, Solder & Protect Your Wire Connection in One Step
Make clean, insulated wire joins without juggling a soldering iron, crimp terminals and separate heat-shrink sleeves. Simply position the wires, apply heat and let the connector do the work.
- ✓Built-in low-temperature solder ring forms the electrical joint
- ✓Hot-melt adhesive rings help create a moisture-resistant seal
- ✓Transparent sleeve lets you inspect wire position before heating
- ✓Four color-coded sizes cover common 26–10 AWG wiring
100 / 300 / 500 / 800-piece options
Solder + seal + insulation in one connector
Low-Temperature Solder
Sealed Connection
No Separate Crimping
Organized Storage Case
Three Functions, One Sleeve
Engineered for a Stronger, Cleaner Repair
Each connector combines a heat-shrink sleeve, internal solder and sealing adhesive so the connection is joined, insulated and protected during the same heating process.
Low-Temperature Solder Ring
Begins melting at approximately 138°C / 280°F to flow around the stripped conductors.
2:1 Heat-Shrink Sleeve
Contracts around the wire to support and insulate the completed joint.
Hot-Melt Adhesive Rings
Seal around the cable jacket to help block moisture and contaminants.
Clear Installation Window
See that both stripped ends overlap correctly before applying heat.
Fast Two-Minute Workflow
Strip. Position. Heat.
A straightforward method for neat repairs in tight spaces and on the go.
2
Center the Conductors
Overlap or twist the stripped ends inside the center solder ring and confirm alignment through the clear sleeve.
3
Apply Even Heat
Rotate the connector while heating until the sleeve shrinks, the adhesive seals and the solder flows. Let it cool fully.
One Kit, Many Repairs
Ready for the Garage, Workshop, Boat or DIY Bench
Useful for low-voltage wiring repairs and installations where a compact, insulated connection is needed.

A Cleaner Finish
Even Shrinking Helps Prevent Weak Spots
Apply heat gradually and rotate the connector so the sleeve contracts uniformly and the solder distributes through the wire strands.
✓
Uniform Heating
Move the heat source back and forth instead of concentrating it in one spot.
✓
Visible Solder Flow
Watch through the transparent sleeve and stop once the solder has flowed around the conductors.
✓
Full Cooling Time
Allow the joint to cool completely before pulling, bending or testing the connection.
Frequently Asked Questions
Before You Start
Do I need a soldering iron or crimping tool?
No separate soldering iron or crimping tool is required. The connector contains an internal solder ring that melts when evenly heated.
What heat source should I use?
A heat gun with a suitable nozzle provides the best control. Apply moderate, even heat and rotate the connector. Avoid holding intense heat in one place because the sleeve can scorch or deform.
Are the connectors waterproof?
The adhesive rings are designed to form a sealed, moisture-resistant joint when the correct connector size is installed and heated properly. The final performance depends on wire condition and installation quality.
How do I choose the right size?
Match the connector to the conductor gauge: white 26–24 AWG, red 22–18 AWG, blue 16–14 AWG and yellow 12–10 AWG.
Can I work on a live wire?
No. Always disconnect the power source and verify the circuit is de-energized before cutting, stripping or joining wires.
Why should the connector cool before handling?
Moving the joint while the solder and adhesive are still soft can weaken the connection or disturb the seal. Let it cool completely before testing or bending the cable.
Keep Reliable Wire Repairs Within Reach
Choose the kit size that matches your garage, toolbox or upcoming project.
Installation note: Use only on de-energized circuits. Match the connector to the wire gauge, use appropriate heat protection and follow applicable electrical and vehicle service requirements.
