TICONN TICONN - 101 Solder Seal Wire Connectors, 300-Piece Heat-Shrink Kit

Polyolefin insulation forms the outer layer of these TICONN solder seal connectors, while an inner solder ring and hot-melt adhesive help join and seal wires in one heat-applied step.

The 300-piece assortment is color-coded for wire gauges from 22 to 10 AWG. That makes it easier to identify a connector size for automotive, marine, RV, motorcycle, trailer, and home electrical wiring projects.

Use a heat gun to shrink the tubing and melt the solder and adhesive, no crimping tool is required. The 2:1 shrink ratio helps the tubing conform around the joint.

What you’ll notice day to day

These butt-splice connectors bring the wire joining and insulating steps together. Once the wires are positioned in the connector, heat activates the solder ring and inner adhesive, while the polyolefin tubing shrinks around the connection. This is a practical format for repairs where a heat-applied splice is preferable to a traditional crimp connector or a separate soldering setup.

The color-coded sizing supports quick selection across a range of common wire gauges. For a boat wiring repair, trailer connection, or automotive electrical job, matching the connector to the wire gauge helps keep the work organized and the finished splice enclosed. The dual-wall construction is designed to insulate the joint and seal out moisture, which is useful in exposed or damp environments.

Key takeaways

The set contains 300 connectors in white, red, blue, and yellow. It is designed for wire gauges from 22 to 10 AWG and has a maximum voltage rating of 125 volts. The stated minimum solder melting temperature is 280°F. These details help you choose the right connector for the wiring task and check that the application fits the product’s ratings.

The solder-and-seal design offers a different approach from connectors that rely on crimping: the joint is made with heat, without a crimping tool. Buyers commonly describe the connectors as easy to use with a heat gun and appreciate the secure connections they can make. Feedback on soldering performance and durability is mixed, with some buyers reporting that the solder did not melt or the wires did not stay joined as expected. Careful placement and even heat application are important to the intended solder-and-seal process.

Usage tips

Select a connector that matches the wire gauge, then insert the wire ends into the butt splice before applying heat. Use a heat gun to warm the connector so the tubing shrinks and the solder and adhesive activate. The product is intended for heat-gun use, not for installation with a crimping tool. Its maximum voltage rating is 125 volts, keep that rating in mind when choosing a connector for an electrical repair.

For a weather-exposed wiring job, the dual-wall design brings insulation and a moisture-sealing adhesive together around the splice. Let the connection cool before handling it as part of the completed repair.

When it makes sense

This assortment suits DIYers and repair projects that use several wire gauges and call for heat-shrink butt splices, such as automotive, boat, RV, motorcycle, trailer, or home electrical wiring. The 300-piece quantity provides connectors for multiple jobs, while the color coding helps identify sizes during installation. You’ll appreciate it if you want a solder-based connection with insulation and adhesive sealing in the same connector, and have a heat gun available for the work.
