Technical Specifications

This 1/2" trade size union features steel construction with female threading on both ends, designed specifically for rigid and IMC conduit connections. The unit measures 1.84" in length with a 1.56" width and height profile, weighing 0.42 pounds for easy handling during installation. Class I, Division 1 and Group B ratings ensure compliance with the most stringent hazardous location requirements, while NEC/CEC compliance guarantees code-compliant installations across North America.

Installation Process

1. Verify conduit ends are properly cut, deburred, and threaded to manufacturer specifications
2. Apply appropriate thread sealant rated for hazardous locations to male conduit threads
3. Thread one conduit end into the first half of the union, ensuring full thread engagement
4. Thread the second conduit end into the opposite half of the union
5. Tighten the union coupling to create a secure, explosion-proof seal
6. Verify proper alignment and secure mounting of the complete conduit run

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and fuel storage areas
• Industrial Manufacturing - Paint spray booths, solvent handling areas, and chemical production lines
• Oil and Gas Operations - Drilling platforms, pumping stations, and pipeline facilities
• Pharmaceutical Manufacturing - Clean rooms and areas with volatile chemical processes
• Grain Handling Facilities - Elevators, mills, and storage areas with combustible dust
• Aircraft Hangars - Fuel handling areas and maintenance facilities
• Marine Applications - Ship engine rooms and fuel storage compartments
• Laboratory Environments - Research facilities handling flammable gases and vapors

Hazardous Location Union Benefits

Unions are essential components in hazardous location electrical systems, providing the flexibility needed for maintenance and system modifications while maintaining explosion-proof integrity. Unlike permanent conduit connections, unions allow electrical contractors to disconnect conduit runs for equipment service, system upgrades, or emergency repairs without compromising the safety ratings required in classified environments.

Why Choose Class I, Division 1 Rating?

Class I, Division 1 represents the highest level of hazardous location protection, designed for environments where ignitable concentrations of flammable gases or vapors exist under normal operating conditions. This Eaton Crouse-Hinds union's Group B rating extends this protection to the most challenging applications involving hydrogen and other highly volatile substances, making it the preferred choice for electrical professionals working in the most demanding industrial environments where safety cannot be compromised.
