Eaton Crouse-Hinds UNY205 SS Union - Group B Rated
Part Number: UNY205 SS
Quick Summary
UNY205 SS is a rugged, stainless steel conduit union designed for rigid/IMC systems in hazardous locations. In harsh environments, installers grapple with corrosion, misalignment, and fittings that fail under load or temperature swings. This union delivers reliable seals and a robust, corrosion resistant connection thanks to 316 stainless steel construction and a tight, male-to-female interface. It carries NEC/CEC compliance and a Group B rating, aligning with hazardous/location classifications such as Class I Div 1 and 2, Class II Div 1 and 2, and Class III. For purchasing teams, the combination of durability, standard size (3/4"), and explicit certification reduces replacement cycles and simplifies procurement while maintaining safety and compliance across facilities.

Eaton Specification Sheet - UNY205 SS
316 stainless steel construction delivers superior corrosion resistance in wet, salty, or chemically aggressive environments. Result: longer service life and reduced maintenance costs. This is particularly valuable in offshore, petrochemical, and mining facilities where material compatibility matters and downtime is costly. || Rigid/IMC compatibility ensures a tight, secure connection with precise alignment, minimizing leak paths and field rework. The business impact is faster installation, fewer callbacks, and improved system integrity. || Group B rating and NEC/CEC compliance provide validated safety for hazardous locations (Class I Div 1/2, Class II Div 1/2, Class III). This reduces regulatory risk and eliminates the need for redundant fittings. || 3/4 inch trade size matches common motor and fixture conduits, simplifying stocking and procurement. Installation benefits include standardized torque recommendations and compatible fittings across Eaton Crouse-Hinds’ UNY family. || Long-term cost of ownership is lowered due to durable material and reusable unions, reducing replacement cycles and inventory needs. In demanding industries, that translates to lower total cost of ownership while maintaining reliability.
