3M 7100167045 Idc Tap Quick Splice Connector 18-16 Awg

Product Description

The 3M 7100167045 is a blue IDC tap quick splice connector designed for making fast, solderless connections to existing wire runs without cutting or stripping. The insulation displacement contact (IDC) termination method pierces the wire insulation on contact, creating a reliable electrical connection between a tap wire and a run wire. This connector handles 18 to 16 AWG wire and accommodates two wire entries. Licensed electricians and low-voltage technicians use these connectors in automotive, residential, and light commercial wiring applications where speed and repeatability are priorities.

This connector is suited for tapping into existing wiring harnesses, adding branch circuits to a run wire, or splicing two wires without a wire nut or solder joint. The blue color coding corresponds to the 18 to 16 AWG wire range, helping technicians select the correct connector size at a glance. Common applications include landscape lighting, automotive accessory wiring, thermostat and control wiring, and other low-voltage signal or power circuits where the wire gauge falls within the rated range.

Key Features

• Rated for 18 to 16 AWG wire gauge range
• Blue color coding for quick, reliable gauge identification
• Accepts two wire entries for tap splice applications
• RoHS 2011/65/EU compliant and UL Listed
• Sold in a package quantity of 25 connectors

Compatibility

Designed for use with 18 to 16 AWG copper wire in tap splice configurations. No specific model or system compatibility was stated in the product data.

Installation Notes

Installation is typically performed by electricians or low-voltage technicians using a pair of pliers or a dedicated IDC splice tool to seat the connector cap fully. Ensure the source circuit is de-energized before making any splice connection. Verify that both the run wire and tap wire fall within the 18 to 16 AWG rated range before crimping — using an out-of-range wire gauge can result in a poor connection or insulation damage. Follow applicable NEC guidelines for the circuit type and environment.
