3M 7100167044 Quick Splice Tap Connector 18-14 Awg 50pk

Product Description

The 3M 7100167044 is a blue quick splice tap connector designed for fast, tool-free wire tapping using insulation displacement contact (IDC) termination. The connector accepts a run wire and a tap wire simultaneously through three wire entries, making mid-run branch connections without cutting the primary conductor. Rated for 18 AWG solid or stranded wire and 14 AWG stranded wire, it is suited for low-voltage wiring tasks in HVAC controls, automotive, and general electrical applications. Each package contains 50 connectors. Installation requires no stripping and no soldering, which reduces labor time on repetitive wiring jobs.

These tap connectors are used wherever a branch connection must be made to an existing wire run without interrupting the circuit. Common applications include thermostat wiring, accessory circuit taps in HVAC systems, trailer wiring, and control panel branch wiring. The IDC design pierces the insulation and clamps the conductor in a single squeeze, making them practical for residential and light commercial electrical and HVAC work. Electricians, HVAC technicians, and automotive wiring installers all use this connector type for quick field splices.

Key Features

• IDC termination — no wire stripping or crimping tools required
• Accepts 18 AWG solid or stranded run wire and 14 AWG stranded tap wire
• Three wire entries support simultaneous run and tap connection
• Blue color coding aids wire gauge identification in the field
• Meets Electrical IDC 801 standard for insulation displacement connectors
• 50 connectors per package with a minimum order quantity of 1 package

Compatibility

Compatible with 18 AWG solid and stranded wire (run) and 14 AWG stranded wire (tap), meeting Electrical IDC 801 standards. Designed as a general-purpose tap splice connector for low-voltage wiring applications across HVAC, electrical, and automotive installations.

Installation Notes

De-energize the circuit completely before making any splice connection. Position the run wire and tap wire into their respective entries and compress the connector with pliers or a dedicated IDC tool until the cap seats fully. Verify that the insulation displacement contact has fully engaged both conductors before closing the circuit. Work performed on branch circuit wiring should comply with applicable NEC requirements for the installation environment.
