• Concrete Tight Design - Prevents concrete infiltration during pour applications, maintaining conduit integrity
• Three-Piece Configuration - Allows for easy installation and adjustment in tight spaces or retrofit applications
• Precision Threading - Ensures secure, vibration-resistant connections that maintain electrical continuity

Installation Advantages

• Dual Conduit Compatibility - Works with both rigid steel and IMC conduit systems for maximum versatility
• Field Adjustable - Three-piece design allows for conduit alignment corrections during installation
• Professional Threading - Clean, precise threads reduce installation time and ensure proper fit
• Compact Profile - 1.38" length minimizes space requirements in crowded electrical installations

Long-Term Performance

• Corrosion Resistance - Malleable iron provides excellent protection against environmental degradation
• Mechanical Strength - Superior tensile strength handles thermal expansion and building movement
• Electrical Continuity - Maintains reliable grounding path throughout the conduit system

Technical Specifications

This 1/2" trade size coupling features malleable iron construction with concrete tight sealing capabilities. The three-piece design measures 1.38" in length and 1.34" in width, weighing 0.23 pounds for easy handling. Compatible with both rigid steel and IMC conduit systems, this coupling meets NEC/CEC standards for ordinary/non-hazardous locations and provides reliable performance in commercial and industrial electrical installations.

Installation Process

1. Verify conduit ends are properly cut, deburred, and threaded to standard specifications
2. Apply appropriate thread compound to male conduit threads for weather sealing
3. Thread the first conduit section into one end of the coupling hand-tight
4. Position the coupling assembly and align with the second conduit section
5. Thread the second conduit section into the opposite end of the coupling
6. Tighten both connections using appropriate wrenches, ensuring proper engagement without over-tightening
7. Verify electrical continuity across the coupling connection for proper grounding

Applications

Perfect for:

• Concrete Pour Applications - Underground electrical systems, foundation work, and concrete-encased conduit runs
• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy-duty electrical distribution
• Municipal Infrastructure - Government buildings, public utilities, and transportation facilities
• Conduit Extensions - Joining conduit sections in long runs or retrofit installations
• Equipment Connections - Motor control centers, switchgear, and electrical panel connections
• Outdoor Installations - Weather-exposed conduit systems requiring superior durability
• High-Vibration Environments - Areas with mechanical equipment or structural movement

Three-Piece Coupling System Benefits

Three-piece couplings offer significant advantages over standard two-piece designs, particularly in retrofit and repair applications. The segmented construction allows electricians to join conduit sections without having to thread the coupling over the entire length of conduit, making it ideal for situations where conduit is already installed or space is limited. This design flexibility reduces labor time and enables connections in previously impossible locations.

Why Choose Malleable Iron Construction?

Malleable iron provides superior mechanical properties compared to standard steel fittings, offering enhanced impact resistance and dimensional stability under stress. This material choice ensures the coupling maintains its integrity under thermal cycling, mechanical stress, and environmental exposure. The concrete tight design prevents infiltration during concrete pours, eliminating costly repairs and maintaining long-term system reliability. Trusted by electrical professionals for over 100 years, Eaton Crouse-Hinds malleable iron fittings deliver the durability and performance required for professional electrical installations.
