Overview

The ABB HUB2-R PVC Coated Zinc Hub Connector is a precision-engineered solution for secure, corrosion-resistant conduit installations in industrial, commercial, and utility environments. Designed for 2-inch pipe sizes (53 metric), this hub connector features a thermoplastic insulated throat rated at 105°C with a UL94 V-0 flammability rating, ensuring reliable performance even in high-temperature applications. The nitrile rubber (Buna-N) sealing ring provides a complete 360° seal, maintaining watertight integrity per NEMA 3R, 4, and 13 enclosure requirements, even when conduit is not perpendicular to the enclosure. The zinc hub is coated with a nominal 0.040-inch (40 mil) PVC layer for superior corrosion resistance, while the red color enhances visibility during installation and maintenance. The hexagonal/splined body and locknut design enable fast, tool-assisted installation with peripheral slots for wrench or hammer use, reducing assembly time by up to 30% compared to standard hubs. The connector accommodates a maximum panel thickness of 0.25 inches (6.35 millimeters) and features sharper, deeper teeth for improved bonding to enclosures. UL Listed (File No. E-23018) and CSA Certified (File No. 4484), including hazardous location certifications for Class II Groups E, F, G and Class III, the HUB2-R meets stringent safety and performance standards. Ideal for grounding and bonding applications in power generation, manufacturing, and infrastructure projects, this connector ensures long-term durability and compliance with NEC/CEC codes.
