Eaton UNF805 SA Union - Rigid/IMC, 3 in Aluminum, Hazardous
Part Number: UNF805 SA
Quick Summary
UNF805 SA Union by Eaton is a rugged conduit union designed for Rigid/IMC installations in hazardous locations. Engineers often contend with heavy, corrosion-prone fittings that slow maintenance and increase downtime; this unit provides a copper-free aluminum option with a secure female connection. It carries NEC/CEC compliance and recognized hazardous location ratings, including Class I divisions 1 and 2, Class II divisions 1 and 2, and Class III. The combination of copper-free construction, a 3 in trade size, and a precision machined interface supports reliable, code-compliant installations even in challenging environments. For procurement and field deployment, this union delivers predictable performance and lower total cost of ownership through easier handling and reduced maintenance.

Eaton Specification Sheet - UNF805 SA
Copper-free aluminum construction reduces weight and improves corrosion resistance, resulting in easier handling and lower maintenance costs on demanding jobsites; the 3 in trade size enables straightforward integration with standard IMC conduits and reduces field modification time. Rigid/IMC compatibility and a female connection simplify alignment and mating with existing fittings, which minimizes rework and accelerates project timelines in complex installations. NEC/CEC compliance and explicit hazardous location ratings—Class I Div 1 and 2, Class II Div 1 and 2, Class III—provide regulatory assurance, speeding approvals and reducing risk in regulated facilities. Precise dimensions (3.44 in length, 2.16 in height and width) and a 2.55 lb weight support predictable enclosure planning and safer handling during installation in confined spaces. Documentation and data sheets, including UL and CSA certifications, facilitate efficient sourcing and qualification for supplier catalogs and design reviews.
