Thomas Betts TNF14-4FB-XV Bullet Connector 16-14 Awg

Product Description

The THOMAS BETTS TNF14-4FB-XV is an insulated bullet connector designed for solderless wire termination in electrical wiring applications. It accepts 16 to 14 AWG wire and features a brass contact with copper sleeve for reliable electrical continuity. The bullet diameter measures 0.153 inches and bullet length measures 0.287 inches. Blue nylon insulation identifies the 16-14 AWG range at a glance and provides a degree of mechanical protection at the termination point. Electricians and wiring technicians use this connector in panel wiring, automotive-style harness repairs, and low-voltage control circuit connections where a quick, secure male bullet termination is required.

This connector is suited for residential and light commercial electrical work, control panel wiring, and field repair applications where 16 to 14 AWG wire is used. The blue nylon insulation color coding follows standard wire connector color conventions, making it easy to match connectors to wire gauge during installation. It is sold in a package quantity of 75, which suits service shops and contractors managing recurring termination work.

Installation Notes

Installation is performed by licensed electricians or qualified wiring technicians. De-energize the circuit completely before terminating or handling connectors. Use a proper ratcheting or calibrated crimp tool rated for insulated connectors to ensure a secure, gas-tight crimp — improper crimping can result in high-resistance joints or pull-out failures. Follow applicable NEC requirements for connector use in the intended circuit environment.
