Key Features & Specifications:

• Brand & Quality: Genuine 3M brand, ensuring high-quality materials and consistent performance.

• Type: Insulated Butt Splice Connector (Barrel Connector)

• Wire Range: 16 to 14 AWG (Accepts two wires of the same size within this range)

• Pack Quantity: 100 Connectors

Primary Applications & Benefits:

• Wire Repair & Extension: The standard solution for seamlessly joining two wire ends, whether repairing a break or adding length to a circuit.

• Secure & Permanent Connection: When properly crimped, the metal barrel creates a cold-weld, gas-tight connection that is highly resistant to vibration and corrosion.

• Built-In Insulation: The color-coded blue vinyl sleeve provides immediate electrical insulation and strain relief, eliminating the need for separate heat shrink or tape.

• Time-Saving & Reliable: Enables quick, professional-grade splices without soldering. The transparent vinyl allows visual inspection of the wire placement.

• Versatile Use: Essential for automotive wiring harness repairs, trailer light wiring, appliance fixes, DIY projects, and industrial maintenance.

How to Use:

1. Strip about 1/4 inch (6mm) of insulation from each wire end.

2. Insert both stripped ends into opposite sides of the connector until they meet in the middle.

3. Crimp firmly at the center of the barrel using a dedicated crimping tool.

4. For added protection, a quick application of heat (from a heat gun) will seal the ends of the vinyl sleeve.
