Overview

The ABB UNF705-G is a 3-piece PVC-coated explosion and dust-ignition-proof UNF female union designed for rigid conduit systems in hazardous and non-hazardous locations. Constructed from electrogalvanized steel with a gray PVC coating, this union provides superior corrosion resistance and durability in demanding industrial environments such as oil, gas, chemical, and mining applications. The 2-1/2 inch (63 metric) pipe size ensures compatibility with standard industrial fittings, while the compact overall length of 3.50 inches (88.90 mm) and diameter of 4.31 inches (109.47 mm) allow for efficient installation in tight spaces. The UNF female thread design simplifies connections to adjacent conduits or fittings, enabling future modifications to the system without system shutdowns. Certified to UL 1203 and CSA C22.2 No. 25/30 standards, the UNF705-G meets NEC/CEC requirements for Class I, Divisions 1 & 2, Groups B, C, D; Class II, Divisions 1 & 2, Groups E, F, G; and Class III hazardous locations. The electrogalvanized steel construction with chromate treatment ensures long-term structural integrity, while the PVC coating enhances resistance to moisture, chemicals, and physical damage. Ideal for use in wet locations, corrosive atmospheres, and areas requiring NEMA 3, 4, 7, or 9 compliance, this union delivers reliable, leak-proof connections in critical applications. Trust ABB Installation Products for dependable performance in explosion-proof conduit systems.
