Eaton Specification Sheet - UNF605
Feraloy iron alloy construction provides exceptional strength and corrosion resistance, reducing replacement cycles and maintenance costs in harsh industrial environments. This rugged alloy is well-suited for explosion-proof unions in chemical plants, mining operations, and offshore facilities. The metallurgy also resists high-temperature exposure and delivers predictable long-term performance under vibration and impact common in process plants. For procurement, the material choice helps reduce spare-part diversity while maintaining compliance with rigorous safety standards. Rigid/IMC compatibility with standard conduit runs simplifies installation and minimizes unexpected leakage paths. The UNF605’s female configuration and 2" trade size streamline field assembly by reducing the need for adapters and extra hardware. The 3.88 in width and height create a compact footprint that fits in tight enclosures, while the 2.69 in depth allows room for connectors and fasteners. The union is designed for ease of mounting with standard fittings, helping technicians complete terminations quickly and consistently. NEC/CEC compliance plus broad hazardous location ratings help you meet regulatory requirements and site standards with confidence. Area classification as Hazardous/Classified Locations and recognized UL/CSA listings reduce audit findings and project risk. Precise dimensions support repeatable field planning: 2.69 in depth, 3.88 in height and width, and a 3.38 lb weight give predictable enclosure integration. The compact, rugged form minimizes downtime during maintenance and simplifies spare-part logistics. Industry insight: selecting a properly rated union like UNF605 lowers total installed cost by consolidating parts, reducing commissioning time, and improving safety in hazardous-area installations.
