3M 7100024642 Insulated Butt Connector 12-10 Awg

Product Description

The 3M 7100024642 is an insulated butt connector designed for splicing two conductors end-to-end in electrical wiring applications. Rated for 12-10 AWG wire, it features chamfered barrel ends that allow fast wire insertion from both sides and a built-in wire stop for accurate positioning before crimping. The insulated sleeve protects the completed splice from abrasion and accidental contact. Licensed electricians and skilled tradespeople use this connector when making inline wire splices in control wiring, panel work, and field-installed circuits where a secure, compact termination is required.

This butt connector is suited for residential and light commercial electrical work, low-voltage control circuits, and equipment wiring where inline wire splices are needed on 12 or 10 AWG conductors. The 12-10 AWG range makes it a common choice for branch circuit splices, appliance wiring, and HVAC control panel connections. It is sold individually with a minimum order quantity of 500 pieces per case, making it practical for stocking on service vehicles or in electrical supply bins.

Key Features

• Chamfered barrel ends allow wire insertion from both ends without snagging
• Built-in wire stop ensures correct conductor positioning before crimping
• Insulated construction protects the splice after termination
• Compatible with 12-10 AWG wire range for broad application coverage
• Crimp-style termination for a reliable, gas-tight connection

Compatibility

Designed as an OEM-style crimp splice connector for use with 12-10 AWG solid or stranded copper conductors in standard electrical wiring applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements. De-energize and lock out the circuit before making any splice connections. Use a calibrated ratcheting crimp tool sized for the wire gauge and connector type to achieve a proper crimp at both barrel ends. Do not attempt to solder or re-crimp a connector that has already been fully seated.
