Feature → Business Impact → Application: The steel construction of the UNY105 delivers rugged durability that reduces replacement costs and downtime for critical conduit connections in explosionproof environments. This enhancement translates into lower maintenance cycles and longer service life, especially in hazardous locations that demand robust fittings for ongoing operations. Application: ideal for installations requiring long-term reliability in rigged conduits and harsh industrial settings. Feature → Business Impact → Application: Rigid/IMC conduit compatibility ensures fast, straightforward assemblies with common conduit systems, cutting installation time and labor cost. This is particularly valuable in tight electrical rooms or retrofit projects where space is at a premium. Application: use in new builds and upgrades with standard rigid/IMC conduit runs. Feature → Business Impact → Application: Group B rating and NEC/CEC alignment mitigate compliance risks and streamline approvals with inspectors, reducing project delays. Application: suitable for Class I/Division 1/2 environments and other hazardous locations requiring documented certifications. Feature → Business Impact → Application: 1/2" trade size and modest dimensions simplify inventory management and field use, improving on-site workflow. Application: preferred for small-diameter conduit networks and space-constrained installations. Feature → Business Impact → Application: UL certification and downloadable datasheets provide quick reference for procurement and audits, supporting consistent quality control. Application: procurement and QA teams rely on official documentation for vendor qualification. Feature → Business Impact → Application: Documentation and catalogs enable faster spec-to-install workflows, minimizing design-review cycles. Application: engineering teams can rapidly validate connectors during initial design and subsequent changes.

FAQs

UNY105 is designed for Class I/Division 1 and 2 hazardous locations with NEC/CEC compliance. When installing, ensure proper mating with rigid/IMC conduit, secure with appropriate fittings, and follow locknut and sealing practices to maintain enclosure integrity. Verify UL listings and consult the Eaton specification sheet for torque and mounting guidance. This reduces ingress risk and maintains performance under demanding conditions.
Yes. UNY105 is specifically specified as a rigid/IMC conduit union with a 1/2 inch trade size and male configuration. The steel body is engineered for reliable mechanical connection and alignment with standard rigid/IMC systems, enabling straightforward field installation and consistent electrical continuity across joints in exposed or harsh environments.
The UNY105 carries NEC/CEC compliance with hazardous location ratings, including Class I, Division 1 and Division 2, and Class II/III per NEC hazardous location guidelines. It is UL-listed for explosionproof use and is designed for Group B environments, which supports safer operations and easier regulatory approvals in hazardous facilities.
The steel construction and Group B rating reduce replacement frequency and maintenance needs in harsh settings, while the compact 2.63" length and 1/2" trade size simplify installation and inventory. Faster assembly lowers labor costs, and UL/NEC/CEC compliance minimizes project delays and audit findings, delivering tangible uptime gains over the equipment’s lifecycle.
