Overview

The ABB UNF505-B is a 3-piece PVC-coated explosion-proof and dust-ignition-proof UNF female union designed for secure conduit connections in hazardous and non-hazardous industrial environments. Constructed from electrogalvanized steel with a light blue PVC coating, this union provides enhanced corrosion resistance and visibility while maintaining grounding continuity in rigid conduit systems. The 1-1/2 inch (41 metric) trade size ensures compatibility with standard rigid conduit installations, featuring an overall length of 2.75 inches (69.85 mm) and an overall diameter of 3.06 inches (77.72 mm). The three-piece design allows for easy assembly and future system modifications, making it ideal for applications requiring frequent adjustments or expansions. Certified for use in wet locations and areas prone to corrosion, the UNF505-B meets hazardous location ratings including Class I, Divisions 1 and 2, Groups C and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2. The PVC coating provides a nominal 0.002-inch (2 mil) blue urethane interior layer and a nominal 0.040-inch (40 mil) PVC exterior layer, bonded to resist environmental degradation. This union is specifically engineered for oil, gas, chemical, and other industries where explosion-proof and dust-ignition-proof electrical installations are mandatory. The electrogalvanized steel construction ensures mechanical strength and durability, while the light blue PVC coating offers UV resistance and improved visibility in industrial settings. The UNF505-B is part of ABB's hazardous location fitting series, designed to integrate seamlessly with rigid conduit systems in both indoor and outdoor applications.
