3M 7100086434 Female Disconnect Nylon Insulated

Product Description

The 3M 7100086434 is a nylon-insulated female disconnect terminal sold in bottles of 100. This quick-disconnect fitting accepts a male tab and creates a secure, insulated electrical connection that resists vibration loosening and accidental contact with live conductors. The nylon sleeve provides dielectric protection over the crimped barrel, making these terminals suitable for low-voltage wiring tasks in HVAC controls, appliance wiring, and panel sub-assemblies. Licensed electricians and HVAC technicians typically use these when terminating 18 AWG conductors to blade-style connectors in control circuits. Internal model designation MNU18-187DFIX appears in 3M product documentation and can be used for cross-reference ordering.

These female disconnect terminals are intended for residential and light commercial electrical work where fast, reliable connections are needed at control boards, relays, and terminal strips. The 100-count bottle format supports service technicians and contractors who install or replace multiple connections in a single job, reducing the need for frequent reordering. Typical applications include thermostat wiring connections, furnace control board harnesses, and low-voltage relay wiring.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician following applicable NEC guidelines. De-energize the circuit completely before crimping or replacing any disconnect terminal. Use a proper ratcheting crimp tool sized for the conductor gauge to ensure a secure, gas-tight crimp. Do not solder over the crimp, as this can create a stress concentration point and reduce long-term reliability.
