Replaces / Cross-Reference Part Numbers

• A universal alternative to traditional butt splices, crimp-on terminals, and separate solder/heat shrink methods.
• Used in place of non-sealed connectors in applications requiring environmental protection.

Compatibility & Fitment

• Fits 12, 11, and 10 AWG solid or stranded copper wires.
• Suitable for DC and low-voltage AC applications including automotive, marine, industrial controls, and outdoor wiring.

When to Replace

• Use for creating new, permanent wire splices in harsh environments.
• Use for repairing damaged, frayed, or corroded wiring sections.
• Replace non-insulated or failing connectors that are exposed to moisture, vibration, or contaminants.

Installation Tips

• Strip approximately 1/3 inch (8mm) of insulation from each wire end.
• Insert wires into the connector, ensuring the stripped ends overlap within the central solder ring.
• Apply heat evenly with a heat gun, focusing first on the center solder ring until it melts and flows.
• Continue applying heat to both ends of the tube until it shrinks and the adhesive lining seals the wire insulation.
• Allow the connector to cool completely before handling or applying stress.
• Visually inspect the connection through the clear tubing to confirm solder flow and a complete seal.
