16-14 AWG Blue Solder Seal Wire Connectors

Key Features

  • Wire Gauge: 16-14 AWG
  • Color Code: Blue
  • Shrinkage Ratio: 3:1
  • Material: Translucent polyolefin tubing with an internal solder sleeve and hot melt adhesive rings
  • Operating Temperature: -55°C to 125°C
  • Minimum Shrink Temperature: 80°C (180°F)
  • Solder Full Melt Temperature: 138°C (280°F)
  • Design: One-piece construction provides a waterproof, insulated, and soldered connection

Replaces / Cross-Reference Part Numbers

  • Universal replacement for standard crimp-style butt connectors for 16-14 AWG wire applications requiring a waterproof seal.

Compatibility & Fitment

  • Fits wire sizes from 1.5mm² to 2.5mm² (16-14 AWG)
  • Suitable for use with solid and stranded copper wire
  • Ideal for automotive, marine, industrial, and home electrical wiring applications

When to Replace

  • For creating new, permanent wire splices
  • When repairing damaged, cut, or frayed wires
  • To protect electrical connections from water, moisture, salt, and corrosion
  • In applications where a reliable, sealed connection is required without a separate soldering iron

Installation Tips

  • Strip wire insulation by approximately 1/3 inch (8mm) on each end.
  • Insert wires into the connector, ensuring the bare ends overlap within the solder sleeve.
  • Apply heat evenly using a heat gun, starting from the center and moving outwards.
  • Watch for the tubing to shrink and the solder to melt and flow, encapsulating the wires.
  • Continue applying heat until the adhesive rings at both ends melt and seal the connection.
  • Allow the connector to cool completely before handling or applying any stress.

FAQ

Solder seal connectors provide a superior, permanent connection by combining soldering, insulation, and sealing in one step. The low-temperature solder ring creates a strong electrical bond, while the heat-shrink tubing creates a waterproof, insulated seal that prevents wire corrosion and pull-out.
You will need a heat gun with a heat-shrink nozzle attachment to ensure even heat distribution. A standard lighter can be used in a pinch, but a heat gun is highly recommended to prevent scorching the tubing and to ensure the solder ring melts evenly around the wire strands.
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 bead of clear adhesive emerge from the ends of the tubing, which indicates a watertight seal.
Yes, these are ideal for both automotive and marine applications. The dual-walled, adhesive-lined tubing is designed to withstand moisture, salt spray, and vibration, making them far more reliable than standard butt connectors in harsh environments.
These blue connectors are specifically designed for 16-14 AWG (American Wire Gauge) wire. Using them on wire sizes outside of this range may result in a poor electrical connection or an incomplete seal.
These connectors are intended for standard low-voltage electrical circuits. They are not designed for high-amperage power transmission or heavy-duty industrial power cables. Always verify that the wire gauge and circuit load are within the safe operating limits for 16-14 AWG connections.
