Eaton Specification Sheet - UNY105 SA
Copper-free aluminum construction delivers corrosion resistance and reduced weight, lowering overall installation effort and long-term maintenance costs while maintaining robust mechanical performance in demanding environments, such as hazardous locations where reliability matters for uptime. Group B rating provides a clear safety margin for potentially explosive atmospheres, helping you meet strict regulatory requirements and avoid costly non-compliance downtimes. The 1/2 inch trade size aligns with common conduit systems, enabling straightforward field assembly and reducing the need for adapters or rework, which accelerates project timelines. Rigid/IMC compatibility ensures secure, vibration-resistant connections, improving long-term seal integrity and wiring protection in harsh environments. Compact dimensions (2.47 in length, 1.5 in width and height) and lightweight design simplify handling, loading, and installation in restricted spaces, cutting labor time and improving site productivity. The part is designed to integrate with the broader UNY conduit fittings family, streamlining procurement and spare-part planning for ongoing maintenance programs.
