Eaton Specification Sheet - UNF505
Heavy-duty steel construction delivers rugged durability that resists corrosion and mechanical wear, reducing maintenance cycles in harsh environments and supporting long service life in explosionproof conduit networks. This translates to lower lifecycle costs and fewer field failures during critical plant downtimes, especially in chemical plants and oil refineries where reliability is non-negotiable. The female UNF505 union supports a 1-1/2" trade size, ensuring precise alignment with mating fittings and a robust seal under vibration, which minimizes leakage paths and rework on long rigid/IMC runs. For project teams, this means faster installation and predictable performance in hazardous locations, backed by a proven family of Crouse-Hinds components that simplifies stocking and replacement. NEC/CEC compliance further reinforces regulatory readiness, enabling smoother inspections and insurance approvals. Area classification as Hazardous/Classified Locations guides safe deployment, reducing the risk of non-compliant installations and costly redesigns. Availability of official specification sheets and catalogs accelerates design reviews and procurement, while compatibility with elbows, tees, and other unions supports scalable system design across the UNF/UNL/UNY family.

FAQs
UNF505 is a female union designed specifically for 1-1/2" trade size rigid/IMC conduits. It integrates with standard Eaton Crouse-Hinds explosionproof fittings, ensuring straightforward alignment, reliable sealing, and minimal risk of misalignment on long conduit runs. This compatibility reduces installation time and lowers field rework, which is especially valuable on large-scale industrial installations in hazardous locations.
UNF505 carries NEC/CEC compliance and is rated for Class I, Division 1 and Division 2 as well as Class II and Class III hazardous locations. It’s designed for Hazardous/Classified Locations, aligning with safety and regulatory requirements across North American markets. Canadian certification references and UL/CSA listings are available in the product literature for audit and qualification purposes.
Yes. UNF505 is explicitly rated for Class I, Division 1 and Division 2, as well as Class II and Class III locations. This makes it appropriate for high-risk areas such as chemical plants and oil refineries, where equipment must withstand hazardous atmosphere classifications while maintaining a reliable conduit connection.
The union’s steel construction provides durability in challenging environments, while its 1-1/2" trade size supports standard conduit sizing. The female design simplifies mating with mating fittings, reducing alignment challenges and seal failures. Combined with NEC/CEC compliance and documented specifications, UNF505 speeds up commissioning and minimizes post-installation service calls in hazardous area projects.
Technical specs are available in Eaton’s UNF505 specification sheet and the Crouse-Hinds catalog pages for unions, elbows, and tees. You can reference the official Eaton PDF and Canadian certification listings to verify ratings and installation procedures, ensuring your design aligns with project requirements and regulatory constraints.
