BUILT FOR REAL-WORLD WIRING
One connector. One heat source. One solid repair.
Skip the awkward crimping and messy solder setup. Slide the stripped wires into the sleeve, apply even heat, and create a compact connection that solders and seals at the same time.
✓
Strong electrical joint
Internal solder melts around the conductor.
✓
Sealed ends
Heat-shrink tubing helps lock out moisture and dirt.
✓
Color-coded sizing
Choose the right sleeve faster for common wire gauges.
WHY IT WORKS
Designed to make wiring repairs simpler
Everything happens inside one transparent heat-shrink sleeve, so you can see the solder flow and the seal form.
💧
Moisture Protection
Adhesive-lined ends shrink tightly around the wire insulation.
🔩
Secure Bond
The center solder ring melts into the conductor for a firm connection.
🎯
Easy Size Matching
Color-coded sleeves help you quickly identify compatible wire ranges.
🚗
Multi-Purpose
Useful for automotive, marine, lighting, audio, home and hobby wiring.
🧰
DIY Friendly
A straightforward option for repairs where space and access are limited.
4 SIMPLE STEPS
From stripped wire to sealed connection
1
Prep the Wires
Strip approximately 1/3 inch (8–10 mm) of insulation from both wire ends.
2
Insert & Align
Slide both wire ends into the sleeve and position the joint under the center solder ring.
3
Apply Even Heat
Rotate the connection while heating until the tubing shrinks and the solder visibly flows.
4
Cool & Check
Allow the joint to cool completely, then check that the seal is tight and the wire is secure.

A CLEANER WAY TO CONNECT
Solder-seal sleeve vs. temporary tape repair
RECOMMENDED
Solder-Seal Connector
- ✓ Soldered electrical connection
- ✓ Heat-shrink protective seal
- ✓ Compact and tidy finish
- ✓ Better suited for lasting repairs
- ✓ Easy visual confirmation while heating
VS
TEMPORARY
Electrical Tape Only
- × Does not create a soldered joint
- × Adhesive can loosen over time
- × Bulkier finished repair
- × Harder to inspect the actual joint
- × Often better as an auxiliary layer
FAQ
Common questions
What heat source should I use?+
A heat gun provides the most controlled, even heat. Keep the heat source moving and rotate the connection to avoid overheating one spot.
How do I know when the connector is ready?+
The tubing should shrink tightly around the wire insulation, and the center solder ring should visibly melt and flow into the conductor.
Can these be used outdoors?+
They are designed for sealed wiring repairs and are commonly used in automotive, marine and outdoor electrical projects. Always select the correct size and install according to your application requirements.
Which connector size do I need?+
Match your wire gauge to the color chart above. The wire should fit comfortably inside the sleeve without excessive empty space.
Do I still need to crimp the connector?+
No crimping step is required for this solder-seal style. The electrical joint is formed by the internal solder ring while the sleeve shrinks around the connection.
