Overview

The ABB HUB1-B PVC Coated Zinc Hub Connector (SKU: HUB1-B) is a precision-engineered solution for secure, corrosion-resistant conduit connections in industrial electrical systems. Constructed from durable zinc with a bonded 0.040-inch (40 mil) PVC coating, this hub connector delivers exceptional resistance to moisture, chemicals, and environmental contaminants. The thermoplastic insulated throat, rated to 105°C and UL94-V0 flammability standards, protects conductors from abrasion and ensures long-term reliability. A nitrile rubber (Buna-N) sealing ring, captured in an optimized groove design, provides a complete 360° seal even when conduit alignment is imperfect, meeting NEMA 3R, 4, and 13 enclosure requirements. The hexagonal/splined body and locknut enable fast, tool-assisted installation with a wrench or screwdriver, while sharper, deeper teeth improve bonding to enclosures. Designed for 1-inch (27 Metric) conduit or pipe, the HUB1-B accommodates panels up to 0.25 inches (6.35 mm) thick, with an overall diameter of 2.00 inches (50.80 mm) and a throat diameter of 1.00 inch (25.40 mm). The light blue PVC coating enhances corrosion resistance and provides clear visual identification in complex installations. CSA certified for hazardous locations (Class II Groups E,F,G and Class III), this connector is ideal for electrical, HVAC, and industrial applications requiring durable, leak-proof connections. Compatible with standard threaded systems, the HUB1-B ensures reliable performance in both new construction and retrofit projects.
