ZORO SELECT Twist-On Wire Connector

This red twist-on connector joins copper conductors in light fixtures and house wiring. It accepts wire combinations from three 18 AWG up to two 10 AWG with two 12 AWG, supporting up to nine conductors total. The thermoplastic shell carries a UL 94 V-2 flammability rating and meets CSA 175604, RoHS and UL E113650 standards.

Installers needing 600 V rated copper splices

Suited for electricians and maintenance crews making standard pigtail or fixture splices within the stated gauge range. Not for aluminum conductor applications, high-temperature environments beyond 221 Degrees F, or voltage requirements above 600 V. Buyers who need a crimp sleeve or push-in style connector should look at a different product type.

Steel contact holds under sustained 600 V load

The steel contact maintains continuity during continuous operation at the maximum rated voltage and temperature. The V-2 rated thermoplastic resists deformation when the connector runs warm for extended periods. Installation with the compatible No. 4 tool ensures consistent torque for long-term reliability in junction boxes.
