Male disconnect for 16–14 AWG wire

These blue male disconnect terminals accept 16 to 14 AWG conductors with a crimp termination and butted seam. Each terminal fits a 0.25 inch wide by 0.032 inch thick tab and carries a 600 V rating. The heat-shrink insulation provides full coverage and seals the connection. A pack contains 25 pieces for field or shop use.

Heat-shrink seal holds up to 221 °F

The heat-shrink tubing shrinks around the crimp joint to create a moisture-resistant seal that remains intact at temperatures up to 221 degrees F. Full insulation coverage prevents accidental contact with the brass barrel. The butted seam and crimp termination maintain mechanical strength under vibration and thermal cycling in automotive and industrial environments.

0.25 inch tab width decides fit

The terminal is built for a 0.25 inch wide male tab with a 0.032 inch thickness, so the tab on the mating component must match those dimensions. If the application uses a different tab width or thickness, this disconnect will not seat correctly. Verify the tab size before ordering to ensure a proper connection.

Questions about this item

How much heat can the blue heat-shrink insulation withstand during continuous operation?

The insulation is rated for a maximum operating temperature of 221 degrees F, suitable for sustained use in typical automotive and industrial environments.

What wire gauges and crimp tool are required to terminate these 0.25-inch male disconnects?

They accept 16 to 14 AWG wire and require a standard crimp tool for the butted-seam barrel with 0.085-inch inside diameter.

Will these CSA and UL listed disconnects mate with existing 0.25-inch female tabs on older equipment?

Yes, the 0.25-inch tab width and 0.032-inch thickness match the industry-standard dimensions used on legacy female receptacles.
