3M 7010304075 Butt Splice Terminal Nylon Crimp-on Yellow 50 Pack

Product Description

The 3M 7010304075 is a fully insulated, crimp-on butt splice terminal designed to create secure inline wire connections in electrical and low-voltage wiring applications. Constructed with a nylon insulation shell, it provides reliable protection at the splice point against abrasion and moisture ingress. At 1.08 inches overall length, it is a compact solution suited for confined wire runs. Electricians and electrical tradespeople use this terminal when joining two wire ends end-to-end without solder, relying on a ratcheting or standard crimp tool to set the connection. Each package contains 50 terminals, making it appropriate for both single-circuit repairs and multi-circuit rough-in work.

This butt splice terminal is used in residential and commercial electrical installations, control wiring, HVAC low-voltage circuits, and panel wiring where inline wire splices are required. The yellow color coding indicates a specific wire gauge range consistent with industry color-coding conventions for crimp terminals. It suits applications where a clean, insulated splice is needed inside junction boxes, control enclosures, or along wire harnesses. Two wire entries allow one conductor per end for a standard butt splice configuration.

Key Features

• Fully insulated nylon shell protects the splice point from abrasion and incidental contact
• Crimp-on connection eliminates the need for solder, reducing install time
• Yellow color coding for quick wire gauge identification in the field
• 1.08 inches overall length fits in tight junction boxes and control enclosures
• Two wire entries support standard inline butt splice configuration
• RoHS 2011/65/EU compliant for use in environmentally regulated installations

Compatibility

Designed as an OEM-style crimp terminal for use with standard crimp tooling compatible with fully insulated nylon butt splice connectors in the yellow gauge range.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements. De-energize the circuit completely before making any splice connection. Use a crimp tool rated for insulated terminals to achieve a proper mechanical and electrical connection — do not use pliers as a substitute. Inspect the nylon insulation for cracking or deformation after crimping to confirm a secure, protected splice.
