22-18 AWG Red Solder Seal Wire Connectors

Key Features

  • Color Code: Red
  • Wire Gauge: 22-18 AWG
  • Connector Type: Butt Splice
  • Insulation Material: Polyolefin
  • Contact Material: Tinned Copper
  • Integrated solder ring and heat-activated adhesive lining for a waterproof seal.

Replaces / Cross-Reference Part Numbers

  • Serves as an alternative for standard crimp-style butt connectors for the specified wire gauge.

Compatibility & Fitment

  • Fits stranded and solid core copper wires from 22 to 18 AWG.
  • Suitable for low-voltage automotive, marine, industrial, and home electrical systems.
  • Creates a waterproof and insulated connection for use in environments exposed to moisture.

When to Replace

  • For creating new, permanent wire-to-wire connections.
  • To repair damaged, cut, or frayed wires.
  • When a secure, sealed, and insulated splice is required.

Installation Tips

  • Strip insulation from wire ends.
  • Insert wires into the connector, ensuring bare ends overlap inside the solder ring.
  • Apply heat evenly with a heat gun until the solder melts and flows.
  • Continue applying heat until the tubing shrinks and the adhesive seals the ends.
  • Allow the connection to cool completely before handling.

FAQ

These connectors are specifically sized for 22-18 AWG (American Wire Gauge) wire, which is commonly referred to as red-coded wire in electrical applications.
Solder seal connectors provide a superior, vibration-resistant connection that is both soldered and waterproof. The heat-shrink tubing creates an environmental seal that prevents corrosion, making them ideal for automotive, marine, and outdoor electrical repairs.
You will need a heat gun with a reflector nozzle to evenly distribute heat around the connector. A standard lighter can be used in a pinch, but a heat gun is recommended to ensure the solder ring melts completely and the tubing shrinks without burning the insulation.
The connection is complete when the solder ring has fully melted and flowed into the wire strands, and the adhesive-lined tubing has shrunk tightly around the wire insulation. You should see a small amount of adhesive bead out from the ends of the tubing, which indicates a proper watertight seal.
Yes. Because these connectors fuse the wire strands into a solid mass of solder and provide strain relief via the heat-shrink sleeve, they perform significantly better than mechanical crimps in high-vibration environments.
These are designed primarily for low-voltage DC applications, such as automotive, trailer, and marine wiring. They are not intended for use on high-voltage household AC mains.
