3M 7000133378 Ring Terminal 12-10 Awg Crimp Yellow 25pk

Product Description

The 3M 7000133378 is a partially insulated circular ring terminal designed for crimp connections on 12 to 10 AWG copper conductors. The terminal features a yellow heat-shrink insulation sleeve that provides a secure, partially insulated finish after crimping. At 1.1 inches in overall length and 0.38 inches in ring width, it fits a No. 10 stud size. The copper contact construction ensures reliable conductivity in panel wiring, control circuits, and equipment termination work. Electricians and electrical technicians install these terminals where a clean, code-compliant ring lug connection is required on standard branch-circuit or low-voltage control wiring.

This ring terminal is suited for residential, commercial, and light industrial electrical applications. Typical use cases include terminating conductors at ground lugs, equipment bonding points, bus bars, and terminal blocks that accept a No. 10 stud. The 12 to 10 AWG wire range makes it a common choice for branch circuit terminations, motor control wiring, and HVAC equipment connections where the conductor gauge falls in that range. This listing is for a package of 25 terminals.

Key Features

• Partially insulated with yellow heat-shrink sleeve for post-crimp identification and protection
• Crimp connection type — no soldering required, compatible with standard ratchet crimp tools
• Accepts 12 to 10 AWG conductors for versatile use across common wire gauges
• No. 10 stud size fits widely used screw and bolt terminals
• Copper contact material provides low-resistance, corrosion-resistant termination
• CSA Certified and UL Listed — meets NEC-compliant installation requirements

Compatibility

Designed as an OEM-style crimp ring terminal for use with 12 to 10 AWG copper conductors terminating at No. 10 stud connections in residential, commercial, and light industrial electrical panels and equipment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit and verify absence of voltage before terminating any conductors. Use a calibrated ratchet-style crimp tool rated for the terminal and wire gauge — do not substitute open-barrel pliers or non-ratcheting tools, as an improper crimp can result in a high-resistance connection or pull-out failure. Inspect the heat-shrink insulation after crimping to confirm full coverage of the barrel.
