3M MTI14-250Q Wire Disconnects

These 3M quick-disconnect terminals accept 16 to 14 AWG copper wire and feature blue nylon insulation with full coverage. A pack contains 25 butted-seam crimp connectors rated for up to 1,000 volts and a maximum operating temperature of 221 degrees Fahrenheit. The tab measures 0.25 inches wide by 0.032 inches thick with a barrel inside diameter of 0.085 inches.

Automotive and appliance wiring technicians

Installers who need a crimp-on tab terminal for solid or stranded wire in the 16 to 14 AWG range will find these suitable. The connectors carry CSA, UL and EU compliance marks for regulated work. They are not for larger gauge wires, smaller gauge wires, solder terminations or ring and spade lug applications.

Crimp tool and mating receptacle required

A compatible crimp tool for butted-seam barrels is needed to terminate the wire securely. The 0.25 inch tab mates with a standard female quick-disconnect receptacle, freeing the installer from solder joints and speeding up harness assembly or repair. The nylon insulation resists heat and vibration in engine compartments or control panels.

Questions about this item

What crimp tool do I need for the 16-14 AWG wire range on these disconnects?

Use a crimp tool rated for 16 to 14 AWG insulated terminals to match the butted seam barrel and the 0.085 in inside diameter.

Will the 0.25 in tab width fit the quick-disconnect terminals already on my harness?

Yes, the 0.25 in tab width and 0.032 in tab thickness match standard 250 series quick-disconnect tabs used on many existing harnesses.

How can I confirm the connection is secure after crimping?

Perform a pull test on the crimped joint and verify the blue nylon insulation fully covers the barrel with no exposed copper.
