3M 7010397396 Butt Splice Terminal Nylon Crimp-on Red 100 Pack

Product Description

The 3M 7010397396 is a fully insulated nylon butt splice terminal used to join two conductors end-to-end in a single crimp connection. The nylon insulation sleeve covers the entire barrel, reducing the risk of accidental contact with adjacent wiring or metal surfaces. The crimp-on design eliminates the need for solder, allowing for fast, repeatable terminations in panel wiring, control circuits, and field repair work. This terminal is color-coded red, indicating compatibility with small-gauge wire ranges standard to that color classification. Electricians, HVAC technicians, and instrumentation technicians regularly use this terminal type in low-voltage and line-voltage wiring assemblies.

This butt splice terminal is suited for residential, commercial, and light industrial wiring applications where a clean, insulated inline splice is required. Common install scenarios include control panel wiring, HVAC low-voltage circuit extensions, appliance repair, and electrical fixture connections. The red color coding allows for quick visual identification of wire gauge range on the job. This item is packaged in quantities of 100, making it practical for shops and service fleets that perform frequent terminations.

Key Features

• Crimp-on connection eliminates solder and speeds up terminations
• Accepts two wire entries for inline conductor splicing
• Red color coding for quick wire gauge identification at a glance
• RoHS 2011/65/EU compliant for use in restricted-substance environments
• Packaged in 100-count quantities for high-volume service use

Compatibility

Designed as an OEM-style replacement and general-use butt splice terminal for crimp-on wiring applications in residential, commercial, and light industrial electrical and HVAC systems.

Installation Notes

Installation is performed by electricians and HVAC technicians using a ratcheting or standard wire terminal crimping tool rated for insulated terminals. Always de-energize the circuit and verify zero voltage with a meter before making any splice connection. Strip conductor insulation to the length specified by the terminal barrel depth, insert fully, and apply a single firm crimp. Do not use pliers or non-rated tools in place of a proper crimping tool, as an incomplete crimp can cause high-resistance connections and potential failure.
