Overview

The ABB 31BK is a black high-temperature wire connector designed for secure, long-lasting splices in industrial applications. Compatible with 18-14 AWG solid or stranded copper wires, this connector ensures reliable electrical connections in high-heat environments up to 105°C. The bulk packaging makes it ideal for large-scale installations or maintenance projects where multiple connectors are required. Unlike standard wire nuts, the 31BK provides a vibration-resistant connection, reducing the risk of loosening over time. It meets UL and CSA safety standards for electrical insulation and is commonly used in HVAC systems, industrial control panels, and machinery wiring. The connector’s compact design allows for efficient use of space in tight junction boxes or panels. For applications requiring heat resistance and durability, the 31BK delivers consistent performance without the need for soldering or crimping. Bulk packaging ensures cost-effective procurement for contractors and OEMs managing multiple installations.
