3M MV14BCK Butt Connector 16-14 Awg Bulk

Product Description

The 3M MV14BCK is a butt splice connector designed for joining 16 to 14 AWG copper conductors in electrical wiring applications. Butt connectors create a secure, in-line termination by accepting a wire into each end of a cylindrical barrel that is then crimped to hold both conductors. This connector is sold in bulk pack format, making it a practical choice for jobs requiring multiple terminations. Electricians and HVAC technicians reach for butt connectors when splicing control wiring, low-voltage circuits, or field-installed wire runs where a reliable mechanical and electrical connection is required.

The MV14BCK is suited for residential and light commercial electrical work, HVAC control wiring, and general low-voltage wiring tasks. The 16-14 AWG range covers common wire gauges found in thermostat wiring, motor leads, and branch circuit extensions. Bulk packaging makes this connector appropriate for service vans, shop stock, and panel shops that regularly perform wire splicing work.

Key Features

• Accepts 16 to 14 AWG copper conductors
• Butt splice design for in-line wire joining
• Bulk pack format reduces per-unit cost for high-volume use
• Crimp termination provides a secure mechanical and electrical connection

Compatibility

Designed as an OEM-style butt splice connector for use with 16 to 14 AWG copper wiring in standard electrical and low-voltage wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians. Always de-energize the circuit and verify zero voltage before making any wire splice. Use a ratcheting or calibrated crimp tool sized for the AWG range to ensure a proper crimp that meets NEC workmanship standards. Avoid over-stripping insulation beyond the barrel depth, as exposed conductor beyond the connector increases the risk of shorts.
