3M 7010319497 Butt Splice Terminal Vinyl Crimp-on Red

Product Description

The 3M 7010319497 is a fully insulated, crimp-on butt splice terminal designed to create secure, inline wire-to-wire connections in electrical wiring applications. The vinyl insulation sleeve covers the entire barrel, protecting the crimped joint from abrasion, moisture, and incidental contact. At 1 inch overall length, this compact terminal suits tight wire runs in panels, junction boxes, and equipment harnesses. Each package contains 100 terminals. The red color coding identifies the wire gauge range for this series, allowing technicians to quickly select the correct terminal during installation. Electricians, panel builders, and low-voltage wiring technicians are the primary installers of this component.

This butt splice terminal is suited for residential, commercial, and light industrial wiring applications where a clean, insulated inline splice is required. Typical use cases include control wiring in HVAC equipment, electrical panel sub-assemblies, appliance wiring, and general-purpose field wiring repairs. The two-entry barrel accepts one wire per end, producing a straight-through splice without exposed conductors. The RoHS 2011/65/EU compliance designation makes these terminals appropriate for projects with environmental compliance requirements.

Key Features

• Fully insulated vinyl sleeve protects the crimped joint along the entire barrel length
• Crimp-on connection method requires no soldering and produces a consistent, repeatable termination
• Red color coding for quick wire gauge identification during installation
• Two-entry barrel design accommodates one wire per end for inline splicing
• RoHS 2011/65/EU compliant for projects with restricted-substance requirements
• Sold in a 100-piece package suitable for stocking service vehicles and shop inventory

Compatibility

Designed as an OEM-style crimp splice terminal for use in general electrical wiring, control circuits, and low-voltage harness applications where a fully insulated inline butt connection is required.

Installation Notes

Installation should be performed by a qualified electrician or wiring technician following applicable NEC requirements and local codes. De-energize the circuit completely before making any splice connections. Use a ratcheting crimp tool rated for insulated vinyl terminals to achieve a proper crimp — do not use pliers or non-rated tools, as under-crimping can result in a high-resistance joint or pull-out failure. Inspect each crimped terminal for a secure wire grip and undamaged insulation before restoring power.
