Technical Specifications

This UNY Series union features 1/2" trade size with male threading for rigid and IMC conduit systems. The steel construction provides superior strength while maintaining the explosion-proof integrity required for Class I, Division 1, Group B hazardous locations. Product dimensions are 2.63" length x 1.56" width x 1.56" height, with a weight of 0.46 pounds. The fitting meets NEC and CEC standards for classified location installations.

Installation Process

1. Verify conduit system is de-energized and properly locked out/tagged out
2. Thread union onto first conduit run, ensuring full thread engagement
3. Apply appropriate thread compound rated for hazardous locations
4. Connect second conduit section to complete the union joint
5. Tighten to manufacturer specifications using appropriate wrenches
6. Verify explosion-proof integrity by checking all threaded connections are fully engaged

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
• Oil and Gas Operations - Drilling platforms, pumping stations, and pipeline facilities
• Paint and Coating Operations - Spray booths, mixing rooms, and finishing areas
• Pharmaceutical Manufacturing - Solvent handling areas and chemical processing zones
• Grain Handling Facilities - Elevators, mills, and processing equipment areas
• Aircraft Hangars - Fuel handling and maintenance areas
• Marine Applications - Ship fuel systems and cargo handling areas
• Industrial Maintenance - Equipment disconnection points requiring periodic access

Hazardous Location Union Benefits

Unions are essential components in hazardous location conduit systems because they provide a safe disconnection point for maintenance and equipment access. Unlike standard couplings, unions allow conduit runs to be separated without cutting or rewiring, making them invaluable for industrial facilities requiring regular equipment maintenance. The explosion-proof design ensures that any internal arcing or sparking is contained within the fitting, preventing ignition of surrounding flammable atmospheres.

Why Choose Steel Construction?

Steel construction provides the mechanical strength and durability required for hazardous location applications where safety cannot be compromised. The robust material withstands the thermal and mechanical stresses of explosion-proof operation while maintaining dimensional stability over decades of service. Eaton Crouse-Hinds steel fittings are engineered to exceed industry standards, providing electrical contractors with the reliability and performance demanded in critical safety applications.
