Ecm Industries Llc 19-004 Yellow Twist-on Wire Connector 9 Pack

Product Description

The ECM INDUSTRIES LLC 19-004 is a yellow, twist-on wire connector sold in a 9-pack for use on 8 to 14 AWG copper wire. The fluted thermoplastic shell resists temperatures up to 221 degrees F, making it suitable for enclosures and junction boxes where heat buildup is a concern. Inside, a square wire spring bites into the copper strands as the connector is twisted on, creating a firm mechanical and electrical connection without the need for tape or additional fasteners. Electricians and HVAC technicians reach for this connector when terminating branch circuits, control wiring, and low-voltage hookups in residential and light commercial work.

This connector is suited for residential and light commercial electrical installations where 8 to 14 AWG copper conductors are being joined. Common applications include junction box splices, fixture connections, panel wiring, and HVAC control circuit terminations. The yellow color coding allows technicians to quickly identify the correct connector size for the wire gauge on hand, reducing errors during high-volume installations or service calls. The carded packaging keeps connectors organized and accessible on the job site.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. Always de-energize the circuit at the breaker and verify absence of voltage before making or breaking wire connections. Strip conductors to the appropriate length, align wire ends, and twist the connector clockwise until snug with no bare copper exposed. Do not use on aluminum wire unless the connector is specifically rated for aluminum conductors.
