Overview

The ABB UNF505-SO PVC Coated Zinc Hub Connector (SKU: UNF505-SO) is a high-integrity conduit fitting engineered for secure, long-lasting electrical installations in industrial and commercial environments. Constructed from durable zinc with a nominal 0.040" (40 mil) PVC coating bonded to the exterior, this connector delivers exceptional corrosion resistance and mechanical strength. The thermoplastic insulated throat is rated to 105°C and meets UL94-V0 flammability standards, providing superior electrical insulation and arc fault prevention. Designed for 1-1/2 inch (41 Metric) conduit, the UNF505-SO features a precisely engineered throat diameter of 1.53 inches (38.86 mm) and an overall diameter of 2.75 inches (69.85 mm). It accommodates a maximum panel thickness of 0.25 inch (6.35 mm), ensuring compatibility with standard enclosures. The integrated nitrile rubber (Buna-N) sealing ring creates a 360° weather-resistant seal, meeting NEMA 3R, 4, and 13 enclosure requirements. This design prevents moisture, dust, and debris ingress, maintaining system integrity in harsh conditions. The connector's safety orange finish enhances visibility during installation and maintenance, reducing the risk of overlooked connections. Its hexagonal/splined body and locknut enable fast, tool-assisted installation, while the sharp, deep teeth provide a penetrating bite for improved bonding to enclosures. Certified by U.L. (File No. E-23018) and CSA (File No. 4484), the UNF505-SO is suitable for hazardous locations, including Class II Groups E.F.G. and Class III per NEC Article 501 and 502. Ideal for electrical contractors, maintenance professionals, and industrial equipment installers, this connector ensures reliable performance in demanding applications such as manufacturing plants, data centers, and outdoor installations. The UNF505-SO is manufactured in the US by ABB Installation Products, a trusted name in electrical infrastructure solutions.
