Eaton Specification Sheet - UNY105 SS
Feature: 316 stainless steel construction delivers exceptional corrosion resistance in wet, chemical, and offshore environments. Business impact: longer service life reduces replacement cycles and maintenance costs, improving uptime. Application: ideal for chemical plants, refineries, and mining operations where exposure to corrosive media and harsh weather is routine. Feature: compatible with rigid and IMC conduit, with a 1/2 inch trade size and male threaded end. Business impact: fast, secure installations minimize field rework and torque losses, while standardizing fittings across projects. Application: fits typical electrical raceways and panel feeders used in industrial automation and process industries. Feature: NEC/CEC compliance and hazardous-location ratings (Class I Division 1 and 2; Class II Division 1 and 2; Class III) provide regulatory confidence. Business impact: reduces audit risk and supports safety programs across refineries, chemical processing, and heavy manufacturing. Application: essential for installations in oil, gas, and chemical processing facilities. Feature: compact geometry—2.47 in length, 1.5 in width, and 1.5 in height—facilitates tight installations without sacrificing strength. Business impact: enables denser wiring schemes and quicker assemblies, cutting installation time on the shop floor and in the field. Application: especially valuable in confined enclosures and rugged equipment cabinets. Feature: precise mating with rigid/IMC fittings promotes leak-free connections and reduces maintenance calls. Business impact: predictable performance lowers total cost of ownership and extends asset life. Application: suitable for ongoing operations in hazardous locations where reliability drives safety and uptime.

FAQs
When installing the UNY105 SS union, ensure proper thread engagement and torque per manufacturer specs to achieve a leak-free seal. Use compatible rigid/IMC conduit and compatible fittings to maintain enclosure integrity. Verify Class I, II, and III location ratings and confirm that the mounting arrangement provides adequate clearance for inspection and future maintenance.
The UNY105 SS union is designed to satisfy NEC/CEC requirements and hazardous-location ratings, including Class I Division 1 and 2, Class II Division 1 and 2, and Class III. Made from 316 stainless steel and rated Group B, it supports compliant installations in chemical, petroleum, and other hazardous environments, helping avoid compliance gaps and audit findings.
Yes. The UNY105 SS union is specified for 1/2" trade size rigid/IMC conduit with a male connection, aligning with standard industrial wiring practices. Its compatibility simplifies procurement and reduces field modification, enabling quicker panel and enclosure assemblies in demanding facilities.
In chemical plants, the 316 stainless steel composition provides excellent corrosion resistance, translating to longer service life and fewer maintenance cycles. The leak-free design minimizes preventive maintenance needs, while robust construction supports infrequent resealing or re-termination, reducing downtime and labor costs over asset life.
Adopting UNY105 SS unions can lower total cost of ownership through extended service life, reduced maintenance, and fewer spare parts due to standardization on a single, durable conduit connection type. The fit with rigid/IMC conduit streamlines installation, accelerates commissioning, and reduces downtime in hazardous-location environments.
