Technical Specifications

This union features 3/4" trade size threading compatible with rigid steel and IMC conduit systems. The steel construction provides superior mechanical protection while meeting Class I, Division 1, Group B hazardous location requirements. Dimensions of 2.69" length × 1.88" width × 1.88" height allow for installation in space-constrained areas. The male configuration ensures proper mating with corresponding female fittings in classified location systems.

Installation Process

1. Verify conduit ends are properly cut, deburred, and threaded to NEC/CEC standards
2. Apply appropriate thread compound rated for hazardous locations
3. Thread union onto first conduit section, ensuring minimum 5 full threads engagement
4. Position second conduit section and complete union connection
5. Tighten to manufacturer specifications using appropriate wrenches
6. Verify flame path integrity and proper thread engagement throughout connection

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 solvent storage areas
• Grain Handling Facilities - Elevators, mills, and processing equipment areas
• Aircraft Hangars - Maintenance areas and fuel handling systems
• Pharmaceutical Manufacturing - Solvent processing and chemical synthesis areas
• Hydrogen Production - Electrolysis facilities and fuel cell manufacturing
• Industrial Maintenance - Equipment connections requiring periodic disconnection

Hazardous Location Union Benefits

Unions are essential components in hazardous location electrical systems where maintenance access is critical. Unlike permanent connections, unions allow electrical contractors to disconnect conduit runs for equipment service without disturbing the entire installation. This capability is particularly valuable in classified locations where system integrity and explosion-proof characteristics must be maintained throughout the installation lifecycle.

Why Choose Steel Construction?

Steel construction provides the mechanical strength and durability required for hazardous location applications where safety cannot be compromised. The material's resistance to impact, vibration, and thermal cycling ensures long-term reliability in demanding industrial environments. Combined with Eaton Crouse-Hinds' precision manufacturing and over 100 years of hazardous location expertise, this union delivers the performance electrical professionals trust for critical safety applications.
