Blue Female Disconnect for 16-14 AWG Wire

These 3M Scotchlok terminals accept 16 to 14 AWG conductors and crimp securely with a butted seam. The nylon insulation provides full coverage and a maximum operating temperature of 221 degrees F. Each pack contains 100 blue disconnects rated for 600 volts.

Suits Automotive and Industrial Crimp Jobs

Installers who need quick-disconnect sockets on 16-14 AWG wire will find the .25 inch tab width and .032 inch tab thickness compatible with standard blade terminals. The product is not for solid-core wire, for wires outside the 16-14 AWG range, or for applications requiring a higher flammability rating than the unrated UL 94 classification.

Verify Wire Gauge and Crimp Tooling

Confirm that your conductors fall within the 16 to 14 AWG range before ordering. Ensure your crimp tool matches the butted-seam barrel and that the .25 inch tab width matches the mating blade in your harness. RoHS compliance is confirmed for regulated environments.

Questions about this item

What wire gauge must I already have on hand to use these 16-14 AWG female disconnects?

They accept 16 AWG minimum and 14 AWG maximum stranded wire, so have that gauge ready before you start crimping.

Will the .25-inch tab width on these blue nylon terminals mate with the older .25-inch blade terminals already in my harness?

Yes, the 0.25-inch tab width is standard for this series, so they slide onto existing 0.25-inch male blades without modification.

After crimping, how can I confirm the tin-plated brass socket is making solid contact?

A firm tug on the wire should not pull the terminal free, and a multimeter across the joint will show near-zero resistance.
