3M 7010397417 Butt Splice Terminal Heat Shrink Crimp-on

Product Description

The 3M 7010397417 is a partially insulated, heat-shrink butt splice terminal designed for making secure, in-line wire connections in electrical and low-voltage wiring applications. The crimp-on connection method delivers a fast, reliable termination without the need for soldering. The heat-shrink insulation sleeve provides a tight, protective seal over the crimp joint once heated, reducing exposure to moisture and mechanical stress. Each package contains 25 terminals. This terminal is installed by licensed electricians, HVAC technicians, and pool and equipment service professionals working on control wiring, field splices, and equipment harness repairs.

This butt splice terminal is suited for residential and light commercial electrical work where a clean, insulated splice is required on control circuits, appliance wiring, and equipment field connections. The yellow color coding indicates a specific wire gauge range consistent with standard industry color conventions for butt splices. It is appropriate for indoor and outdoor applications where the heat-shrink sleeve provides added protection against environmental exposure at the splice point.

Key Features

• Partially insulated heat-shrink sleeve seals the crimp joint when heated
• Crimp-on connection eliminates the need for soldering
• Yellow color coding for quick gauge identification at the workbench
• Sold in a 25-piece package for job-site or shop stocking
• Compact, lightweight design at 0.5 pounds per package of 25

Compatibility

Designed as an OEM-style replacement and general-use butt splice terminal for in-line wire splicing on electrical control circuits, appliance wiring harnesses, and equipment field connections where a partially insulated crimp termination is specified.

Installation Notes

Installation should be performed by a qualified electrician or trained technician in accordance with applicable NEC requirements. De-energize the circuit completely before making any splice connection. Use a calibrated ratcheting crimping tool appropriate for the terminal gauge to ensure a proper mechanical crimp. After crimping, apply uniform heat with a heat gun to shrink the insulation sleeve evenly around the splice joint.
