Eaton Crouse-Hinds UNY215 SA Union - Group B rated
Part Number: UNY215 SA
Quick Summary
UNY215 SA union is a rugged, explosionproof conduit fitting for rigid/IMC installations in hazardous locations. Engineers often face the dual challenge of meeting stringent safety codes while keeping field assembly simple in tight spaces. This union is designed to address that pain by delivering NEC/CEC compliance, Class I/II/III ratings, and a copper-free aluminum body for lighter weight. With Group B rated construction and UL and CSA certification support, it provides reliable performance where explosive atmospheres are a concern. Its 1/2" female to 3/4" male trade size and straightforward fit minimize tool time, shorten commissioning, and reduce long-term maintenance costs. Operators gain uptime and predictable sourcing when standard Eaton Crouse-Hinds catalogs and spec sheets are referenced during procurement.

FAQs
The UNY215 SA union is recommended for rigid/IMC conduit runs in hazardous locations that require NEC/CEC compliance and Class I, II, and III ratings. It is designed for chemical processing, oil and gas facilities, and other environments where explosion protection and reliable electrical connections are critical, helping installers meet safety and performance criteria with a single, compatible fitting.
Key specifications include conduit type (Rigid/IMC), gender (Male), ends (Female on end 1 and Male on end 2), material (Copper-free aluminum), trade size (1/2" F to 3/4" M), and area classification (Hazardous/Classified Locations). It also carries NEC/CEC standards alignment and Group B rating, all of which influence durability, weight, and ease of installation in risk-prone environments.
Yes. The UNY215 SA is designed forRigid/IMC conduit and features a 1/2" female to 3/4" male trade size with male/female ends, facilitating direct mating with common conduit components. This compatibility reduces the need for adapters, simplifies field assembly, and supports quicker commissioning in new installations or retrofits.
The UNY215 SA carries NEC/CEC compliance with hazardous location ratings (Class I, Division 1 & 2; Class II, Division 1 & 2; Class III) and area classification for Hazardous/Classified Locations. It is supported by UL and CSA certification programs, with additional documentation such as Eaton’s specification sheets to aid audits and supplier qualification.
Choosing UNY215 SA yields a measurable ROI through lighter copper-free aluminum construction for easier handling, reduced corrosion risk, and longer service life in harsh environments. The design supports faster installation, fewer mismatch issues, and easier procurement with comprehensive documentation, which lowers downtime and total cost of ownership over the equipment lifecycle.
