3M 7000133391 Female Wire Disconnect 16-14 Awg 25 Pack

Product Description

The 3M 7000133391 is a fully insulated female wire disconnect designed for crimp-style electrical terminations in HVAC, appliance, and general electrical service work. The connector features a nylon heat-shrink insulation sleeve in blue, providing a secure, moisture-resistant seal after termination. It accommodates 16 to 14 AWG stranded or solid wire and accepts a 1/4 inch tab width male terminal. The brass contact core is plated with titanium nitride (TiN) to resist corrosion and maintain low contact resistance over time. Each package contains 25 connectors.

This disconnect is suited for residential and commercial electrical connections where a reliable, removable crimp terminal is required. Common applications include control board wiring in furnaces and air handlers, fan motor lead connections, appliance wiring harnesses, and low-voltage control circuit terminations. The blue color coding identifies the 16-14 AWG wire range at a glance during installation and inspection, reducing the chance of mismatched terminations in multi-wire panels or junction boxes.

Key Features

• Fully insulated nylon heat-shrink sleeve for a sealed, corrosion-resistant crimp joint
• Accepts 16-14 AWG wire with a crimp connection type
• 1/4 inch tab width fits standard male quick-disconnect terminals
• Brass contact with TiN plating for low-resistance, long-service connection
• Blue insulation color-codes the 16-14 AWG range for fast identification
• RoHS 2011/65/EU compliant for use in restricted-substance environments

Compatibility

Designed as an OEM-style crimp disconnect for use with standard 1/4 inch male quick-disconnect tab terminals on 16-14 AWG copper conductors in residential and light commercial electrical and HVAC control wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. De-energize and lock out the circuit before terminating or removing any disconnect. Use a calibrated ratcheting crimp tool rated for insulated heat-shrink terminals to ensure full compression of both the wire crimp and the strain-relief section. Apply heat evenly with a heat gun to activate the heat-shrink sleeve after crimping for a sealed connection.
