How to Install

  1. Strip the wire ends and slide the correct connector over one wire.
  2. Overlap or twist the conductors inside the solder ring.
  3. Heat evenly with a heat gun until the solder flows and both adhesive rings seal.
  4. Allow the splice to cool before pulling or energizing the circuit.

Tip: Use a heat gun with controlled airflow. Do not use an open flame, which can scorch the tubing or create uneven solder flow.

Do these connectors need a crimping tool?

No. They are installed with controlled heat; the solder ring forms the electrical connection while the tubing shrinks around the splice.

Are they waterproof?

When correctly installed, the adhesive rings create a moisture-resistant seal. Always verify the splice before use in demanding or submerged environments.

Which size should I choose?

Match the connector color to the conductor gauge, not the outer insulation diameter. The mixed kit is useful when a project includes several wire sizes.

Can I use them for automotive and marine wiring?

Yes, they are designed for common automotive, marine, trailer, and low-voltage electrical repairs when installed with the correct heat and wire preparation.
