Why choose these solder seal connectors
Weatherproof and moisture-resistant
Heat shrink tubing and built-in hot-melt adhesive combine to block moisture and corrosion, making these ideal for demanding environments.
Quick size identification
Color-coded connectors let you match the right size at a glance: white for 26-24 AWG, red for 18-22 AWG, blue for 16-14 AWG, and yellow for 12-10 AWG.
Built for tough repairs
Perfect for fixing or extending wires in vehicles, boats, trailers, and other places where a permanent, moisture-resistant connection matters.
Setup
How to make a waterproof splice
No electrician, no wiring, no fuss.
-
Slide the connector on
Place the connector over the two wire ends you want to join, making sure they meet inside the solder ring.
-
Heat with a heat gun
Apply heat evenly with a heat gun. The solder melts and flows around the wires, creating a secure connection.
-
Let it seal
As the heat shrink tubing contracts, the built-in hot-melt adhesive activates, forming a weatherproof, corrosion-resistant seal.

Comparison
Solder seal connectors vs. standard crimp connectors
Not all products in this category are built the same.
Feature
SmartPicksWorld
Typical alternative
Connection method
Self-soldering design that melts and bonds when heated with a heat gun
Requires a separate crimping tool and relies on mechanical pressure
Waterproofing
Heat shrink tubing plus built-in hot-melt adhesive blocks moisture and corrosion
Often lacks a seal, leaving connections exposed to moisture
Strain relief
Heat shrink tubing provides insulation and strain relief in one step
May need additional tape or sleeving for strain relief
Joint quality
Tin-plated terminal ring creates a durable, low-resistance joint
Crimp quality depends on tool calibration and technique
Size selection
Color-coded sizes for quick identification across four AWG ranges
Sizes may not be color-coded, requiring careful measurement

Frequently asked questions
Everything you might want to know before you order.
How do these solder seal connectors work?
Each connector contains a built-in solder ring and heat shrink tubing. When you heat it with a heat gun, the solder melts and flows around the wire ends to create a secure connection, while the tubing shrinks to insulate and seal the joint.
Do I need a soldering iron to use these connectors?
No. The self-soldering design activates with a heat gun, so you can make professional-grade splices without a soldering iron.
What wire sizes do the color-coded connectors fit?
The connectors are color-coded by size: white fits 26-24 AWG, red fits 18-22 AWG, blue fits 16-14 AWG, and yellow fits 12-10 AWG, so you can quickly pick the right one for your wire gauge.
Are these connectors waterproof?
Yes. The heat shrink tubing and built-in hot-melt adhesive create a weatherproof seal that blocks moisture and corrosion, making them ideal for marine, automotive, and household wiring repairs.
Where can I use these connectors?
They are ideal for fixing or extending wires in vehicles, boats, trailers, and other demanding environments where a permanent, moisture-resistant connection matters.
