Quick-Disconnect Female Terminals
This pack contains twenty-five red insulated female disconnects made by 3M for 22 to 18 AWG wire. Each terminal accepts a 0.25-inch by 0.032-inch tab and is terminated with a crimp barrel. The nylon insulation provides full coverage and the contact is tin-plated brass. They are rated for up to 600 volts and a maximum operating temperature of 221 degrees Fahrenheit.
Automotive and Low-Voltage Wiring Jobs
These disconnects suit technicians making quick-connect joints in vehicle harnesses, marine circuits or general low-voltage equipment. Builders needing a larger wire range, a different tab width or a fully sealed environmental connector should look at other products. The butted-seam barrel and crimp-only termination also mean they are not intended for soldered or screw-down applications.
0.25-Inch Tab Width and 22-18 AWG Range
The single specification that decides fit is the 0.25-inch tab width combined with the 22 to 18 AWG wire range. If the mating tab is narrower, wider or thicker than 0.032 inch, or if the conductor falls outside the stated gauge window, the terminal will not make a reliable connection.

Questions about this item
What barrel inside diameter fits the 22 to 18 AWG wire range?
The barrel inside diameter is .08 in, sized for 22 to 18 AWG conductors.
How do I crimp these quick-disconnect terminals, and what step is often missed?
Strip the wire, insert it fully into the .08 in barrel, then crimp with a ratchet tool matched to 22-18 AWG; the step often missed is verifying the insulation sits inside the nylon cover before crimping.
When should I replace a terminal that has seen 221 °F operating temperature?
Replace any terminal showing discoloured tin plating, cracked nylon insulation, or a loose grip on the .25 in tab after exposure to the 221 °F maximum temperature.
