3M 7000005878 Idc Connector Double Run Tap 18-14 Awg

Product Description

The 3M 7000005878 is an insulation displacement connector (IDC) designed to electrically connect a tap wire end to a through run wire while fully insulating the joint. Built for tap and parallel splicing applications, this light blue connector accepts 18 to 16 AWG solid or stranded wire and 14 AWG stranded wire. The housing is flame retardant and rated for continuous operation up to 221 degrees F (105 degrees C), making it suitable for demanding electrical environments. Licensed electricians and low-voltage technicians working in panel wiring, branch circuits, and in-wall splicing applications rely on this connector for fast, reliable field terminations.

This connector is suited for residential and light commercial electrical installations where tap or parallel splice connections are required without cutting the through run wire. The maximum insulation outer diameter accepted is 0.145 inches. The suggested application tool is the E-9BM Crimping Tool, which ensures consistent termination force and proper insulation displacement. Sold in bags of 500 and cases of 5000, this connector is a standard stocking item for electrical contractors and service technicians.
