Eaton Crouse-Hinds 1" Rigid/IMC Union, Steel, Class I Division 1 Rated

Hazardous Location Union for Safe Conduit Connections in Classified Areas

The Eaton Crouse-Hinds 1" Rigid/IMC Union is a professional-grade hazardous location fitting engineered for safe conduit connections in Class I, Division 1 environments. This steel union delivers reliable performance and code compliance for electrical contractors working in classified locations where explosive atmospheres may be present.

Key Features & Benefits

Hazardous Location Safety

  • Class I, Division 1 Rating - Approved for use in locations where flammable gases or vapors may be present during normal operations
  • Group B Classification - Suitable for hydrogen and other highly hazardous gas environments
  • Explosion-Proof Design - Contains internal explosions and prevents ignition of surrounding atmosphere
  • NEC/CEC Compliant - Meets all applicable electrical code requirements for classified locations

Professional Construction

  • Steel Construction - Provides exceptional strength and durability for demanding industrial environments
  • Precision Threading - Ensures proper flame path maintenance and secure connections
  • Female Configuration - Designed to accept male threaded conduit or fittings on both ends
  • Compact Design - 2.19" width and height with 2.09" depth for space-efficient installations

Installation Efficiency

  • Union Design - Allows for easy disconnection and reconnection without disturbing connected conduit runs
  • 1" Trade Size - Compatible with standard 1" rigid and IMC conduit systems
  • Lightweight Profile - At 0.77 pounds, reduces installation fatigue while maintaining strength

Technical Specifications

This 1" trade size union features steel construction with female threading on both ends, specifically designed for rigid and IMC conduit applications. The fitting measures 2.19" in width and height with a 2.09" depth, weighing 0.77 pounds. It carries Class I, Division 1, Group B hazardous location ratings and complies with NEC/CEC standards for classified area installations.

Installation Process

  1. Verify conduit ends are properly cut, deburred, and threaded to standard specifications
  2. Apply appropriate thread compound rated for hazardous locations to male threads
  3. Thread conduit or male fittings into both ends of the union hand-tight
  4. Use appropriate wrenches to tighten connections, ensuring proper thread engagement
  5. Verify all connections maintain required flame path clearances
  6. Test installation for proper grounding continuity through the union

Applications

Perfect for:

  • Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
  • Oil and Gas Operations - Drilling platforms, pump stations, and pipeline facilities
  • Paint Spray Booths - Automotive finishing and industrial coating operations
  • Grain Handling Facilities - Elevators, mills, and processing equipment areas
  • Aircraft Hangars - Maintenance areas and fuel handling zones
  • Pharmaceutical Manufacturing - Clean rooms and solvent handling areas
  • Marine Applications - Ship engine rooms and fuel system installations
  • Mining Operations - Underground electrical systems in potentially explosive atmospheres

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 electrical contractors to separate conduit runs without cutting or disturbing the entire installation, making them invaluable for equipment connections that require periodic maintenance in classified areas.

Why Choose Steel Construction?

Steel construction provides the mechanical strength and flame path integrity required for Class I, Division 1 applications. The material's durability ensures long-term performance in corrosive industrial environments, while its thermal properties help maintain proper explosion-proof characteristics. Eaton Crouse-Hinds steel fittings are engineered to withstand the demanding conditions of hazardous locations while providing decades of reliable service.
