Ecm Industries Llc 19-002 Blue Twist-on Wire Connector 14 Pack

Product Description

The ECM INDUSTRIES LLC 19-002 is a 14-pack of blue, small-sized twist-on wire connectors designed for fast, reliable splicing of 22 to 16 AWG copper conductors. The fluted thermoplastic shell resists temperatures up to 221 degrees F, making these connectors suitable for use in warm or confined spaces such as junction boxes, control panels, and HVAC equipment enclosures. The square-wire spring interior bites into copper strands as the connector is twisted on, creating a secure mechanical connection without the need for tape or additional fasteners. Color coding helps technicians quickly identify conductor size ranges during installation.

These twist-on connectors are suited for light-gauge copper wiring applications in residential and light commercial settings. Electricians, HVAC technicians, and plumbers use them when making low-voltage control wiring connections, splicing thermostat wires, or completing general-purpose electrical terminations inside listed enclosures. The 22 to 16 AWG range covers common control circuit conductors found in furnaces, air handlers, thermostats, and similar equipment.

Compatibility

Designed as a general-purpose twist-on wire connector for 22 to 16 AWG copper conductors in standard residential and light commercial electrical and control wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified trade professional in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify it is locked out before making any wire connections. Twist the connector clockwise onto stripped conductor ends until it seats firmly and the wires do not pull free under a light tug test. Do not use with aluminum conductors unless the connector is specifically rated for aluminum.
