3M 7000133654 Vinyl Insulated Butt Connector 12-10 Awg

Product Description

The 3M 7000133654 is a vinyl insulated butt splice connector rated for 12-10 AWG wire, sold in packs of 10 bags. It is designed for making inline wire-to-wire connections in electrical, HVAC control wiring, and general low-voltage applications. The connector features chamfered barrel ends that allow fast wire insertion from both ends, and a built-in wire stop that ensures correct conductor positioning before crimping. Both ends must be crimped to complete a secure termination. Electricians, HVAC technicians, and other trades rely on this type of connector for clean, insulated splices in panel, junction box, and field-wiring work.

This butt connector is suited for residential and light commercial wiring tasks where a reliable inline splice is needed on 12-10 AWG conductors. Typical applications include control circuit wiring, equipment hookup, and repair splices in conduit or open wiring runs. The vinyl insulation provides a degree of protection against abrasion and incidental contact after termination.

Key Features

• Accepts 12-10 AWG wire range for versatile conductor compatibility
• Chamfered barrel ends allow fast, guided wire insertion from both sides
• Built-in wire stop ensures correct conductor positioning before crimp
• Vinyl insulation protects the completed splice
• Requires crimping at both ends for a secure connection
• Sold in packs of 10 bags for bench and field stocking

Compatibility

Designed as an OEM-style replacement and general-use butt splice connector for applications requiring inline termination of 12-10 AWG conductors.

Installation Notes

Installation should be performed by a qualified electrician or licensed trade professional in accordance with applicable NEC requirements. De-energize the circuit completely before stripping conductors or inserting wires into the connector. Use a calibrated ratcheting wire crimper appropriate for insulated butt connectors to ensure a proper crimp at both barrel ends. Do not substitute pliers or non-rated tools for the crimping operation, as an improper crimp can result in a failed or high-resistance connection.
