3M 7000133392 Male Wire Disconnect 16-14 Awg 25 Pack

Product Description

The 3M 7000133392 is a male crimp-style wire disconnect terminal designed for secure, insulated electrical connections in demanding trade applications. Featuring full nylon heat-shrink insulation in blue, this disconnect accepts 16-14 AWG wire via a crimp connection and offers a 1/4 inch tab width for standard mating receptacles. The copper contact with tin (TiN) plating resists corrosion and maintains reliable conductivity over time. Each package contains 25 terminals. Electricians and HVAC technicians routinely use these terminals for control-wiring repairs, equipment harness fabrication, and service replacements where a moisture-resistant, fully insulated crimp termination is required.

This terminal is suited for low-voltage control circuits, field wiring repairs, and harness assembly in residential and light commercial HVAC systems, electrical panels, and appliance wiring. The heat-shrink insulation provides additional environmental protection compared to standard vinyl-insulated disconnects, making it appropriate for installations exposed to vibration, moisture, or temperature cycling. Sold in a 25-count package, it is a practical bench or service-van stock item for any electrical trade professional.

Key Features

• Full nylon heat-shrink insulation provides environmental and mechanical protection beyond standard vinyl terminals
• Accepts 16-14 AWG wire via crimp connection for fast, tool-based termination
• 1/4 inch tab width mates with standard quick-disconnect receptacles
• Copper contact with TiN plating for corrosion resistance and long-term conductivity
• RoHS 2011/65/EU compliant for use in regulated installations
• 25 terminals per package — practical quantity for stocking and service use

Compatibility

Designed as an OEM-style replacement terminal compatible with standard 1/4 inch male quick-disconnect applications using 16-14 AWG wire in electrical and HVAC control wiring.

Installation Notes

Installation is typically performed by licensed electricians or HVAC technicians. De-energize and lock out the circuit before terminating any wiring. Use a calibrated ratchet crimp tool rated for insulated terminals to achieve a proper mechanical crimp; do not over-crimp or use pliers as a substitute tool. Apply heat evenly to the shrink sleeve with a heat gun after crimping to activate the adhesive liner and complete the seal. Follow applicable NEC requirements for wire gauge, terminal rating, and circuit protection.
