Eaton Crouse-Hinds UNF1005 UNF Union - Group B rated
Part Number: UNF1005
Quick Summary
UNF1005 is a rugged explosionproof conduit union designed for reliable connections in hazardous locations. Installing fittings in Class I/II environments often suffers from certification delays, corrosion concerns, and fitment mismatches. It carries NEC/CEC standards with NEC hazardous ratings for Class I Division 1 and 2, Class II Division 1 and 2, and Class III, ensuring compliance across diverse process areas. For procurement teams, UNF1005 offers Group B rated performance and a durable Feraloy iron alloy body, delivering safer, faster installations and predictable maintenance of explosionproof conduit unions in industrial electrical systems. This translates to lower lifecycle costs and simpler supplier qualification for projects in oil, gas, chemical, and mining sectors. By specifying a single, clearly rated connector, engineers can reduce field rework and inspection findings.
