Eaton Specification Sheet - UNY205 SA
Copper-free aluminum construction reduces weight and corrosion exposure, delivering long-term durability in harsh environments while lowering handling and installation effort. Feature → Business Impact → Application: lighter components translate to easier field assembly and less fatigue in tight spaces, especially in offshore or refinery settings where crane time is costly and safety is paramount. Conduit type is rigid/IMC with male connectors, enabling a fast, secure termination that reduces field rework and improves plant uptime. Group B rated design supports hazardous locations, giving engineers confidence during commissioning and ongoing compliance audits. The 3/4 inch trade size matches widely used conduit runs, simplifying stocking and reducing inventory costs across multiple projects. NEC/CEC compliance and UL/CSA certifications deliver regulatory assurance, accelerating project approvals and reducing third-party testing fees. Weight and corrosion resistance of copper-free aluminum provide an attractive lifecycle cost compared with traditional steel unions, particularly in damp or corrosive environments. This product is compatible with standard Eaton Crouse-Hinds UNY fittings family, enabling plug-and-play installation and faster maintenance planning.
