Eaton Crouse-Hinds UNF012 Union - Hazardous Locations
Part Number: UNF012
Quick Summary
UNF012 Union is a rugged conduit union that joins rigid or IMC conduits in hazardous locations. Installers often struggle with misalignment, sealing gaps, and compliance audits in harsh environments, which can slow projects and increase risk. This unit meets NEC/CEC standards and carries NEC hazardous location ratings (Class I, II, III) and UL certification for explosionproof service, supporting safe operation in classified areas. The combination of a Feraloy iron alloy body and a 5" trade size delivers robust durability and compatibility with standard conduit systems. This results in faster installations, reduced rework, and easier ongoing maintenance, while enabling engineers to meet stringent safety and compliance requirements for critical industrial applications.

Eaton Specification Sheet - UNF012
Material strength and durability are provided by a Feraloy iron alloy body, which resists impact and harsh chemical exposure in demanding facilities. This translates to lower maintenance costs and fewer replacement cycles, especially in chemical plants or petrochemical environments where reliability is critical. The UNF012 is designed for rigid/IMC conduit and features a female connection, delivering secure, vibration-resistant unions that simplify field assembly and reduce installation errors. In practice, this means quicker hookups and a tighter seal, minimizing ingress paths for dust, moisture, or hazardous atmospheres and supporting longer service life in hazardous locations. The 5" trade size supports typical large-diameter conduit runs, enabling efficient cable management and compatibility with standard electrical infrastructure. NEC/CEC compliance and UL explosionproof certification address regulatory concerns, facilitating design-in for safety-critical projects and helping procurement justify higher upfront costs with documented risk mitigation. Installation advantages include straightforward alignment with matching couplings and standardized conduit systems, reducing training needs for technicians and accelerating project timelines. These attributes combine to deliver measurable results: improved safety, reduced rework, and better total cost of ownership in industrial automation and electrical installations.

FAQs
UNF012 is designed for rigid/IMC conduit and uses a female union interface, allowing quick, secure mating with standard fittings. This compatibility reduces alignment issues and sealing gaps, leading to faster field installs and fewer callbacks for rework in harsh environments.
UNF012 carries NEC/CEC standards with NEC hazardous location ratings including Class I, Division 1 & 2, Class II Division 1 & 2, and Class III, plus UL certification for explosionproof service and area classification in hazardous locations.
Yes. Built for hazardous/classified locations, UNF012 is an explosionproof conduit union constructed from Feraloy iron alloy and certified for use in explosive atmospheres, meeting UL and NEC/CEC requirements for safe operation.
UNF012 features a 3.81 inch depth, 8.19 inch height and width, and weighs 16.15 pounds, with a 5 inch trade size. These dimensions help engineers plan clearance, mounting, and routing in compact or cluttered electrical enclosures.
Ensure mating with standard rigid/IMC conduits using compatible fittings, follow NEC/CEC guidelines for hazardous locations, and rely on UL certifications to satisfy regulatory requirements. The rugged Ferroy alloy body extends service life, reducing maintenance and downtime, delivering a favorable total cost of ownership.
