Professional-Grade Concrete Tight Coupling for Heavy-Duty Electrical Installations

The Eaton Crouse-Hinds 3/4" Three-Piece Conduit Coupling is a premium malleable iron coupling engineered for demanding rigid and IMC conduit connections. This concrete tight coupling delivers superior strength and reliability for commercial and industrial electrical installations where maximum durability is essential.

Key Features & Benefits

Superior Malleable Iron Construction

• Malleable Iron Material - Stronger than steel construction provides exceptional impact resistance and long-term durability
• Concrete Tight Design - Engineered seal prevents concrete infiltration during pour operations
• Three-Piece Configuration - Allows for easy installation and adjustment in tight spaces
• Professional-Grade Finish - Corrosion-resistant coating ensures decades of reliable service

Installation Efficiency

• Dual Conduit Compatibility - Works with both rigid steel and IMC conduit systems
• Precision Threading - Smooth, accurate threads ensure proper fit and grounding continuity
• Contractor-Friendly Design - Three-piece construction simplifies installation in confined areas
• Field Adjustable - Allows for conduit alignment corrections during installation

Code Compliance & Safety

• NEC/CEC Compliant - Meets all National and Canadian Electrical Code requirements
• Grounding Continuity - Maintains electrical continuity throughout the conduit system
• Ordinary Location Rated - Suitable for standard commercial and industrial environments

Technical Specifications

This 3/4" trade size coupling features malleable iron construction with concrete tight sealing capabilities. The three-piece design measures 3.42 inches in length, 1.39 inches in width, and 0.97 inches in height, weighing 0.35 pounds. Compatible with both rigid steel and IMC conduit systems, this coupling maintains NEC/CEC compliance standards and provides reliable grounding continuity for ordinary location installations.

Installation Process

1. Verify conduit ends are properly cut and deburred for smooth threading
2. Apply appropriate thread compound to conduit threads as required
3. Thread the first piece of the coupling onto the first conduit section
4. Position the center ring and align conduit sections as needed
5. Thread the second coupling piece onto the second conduit section
6. Tighten both coupling pieces to ensure proper seal and grounding continuity

Applications

Perfect for:

• Concrete Pour Applications - Underground electrical systems, foundation work, concrete slab installations
• Commercial Buildings - Office complexes, retail centers, hospitals, schools
• Industrial Facilities - Manufacturing plants, processing facilities, warehouses
• Heavy-Duty Installations - Motor control centers, electrical distribution panels, switchgear connections
• Municipal Infrastructure - Government buildings, public facilities, utility installations
• Conduit Extensions - Joining conduit runs, equipment connections, panel feeds
• Retrofit Projects - Electrical system upgrades, conduit repairs, system modifications
• Outdoor Installations - Where superior corrosion resistance is required

Three-Piece Coupling System Benefits

Three-piece couplings offer significant advantages over standard two-piece designs, particularly in tight installation spaces and concrete pour applications. The separable design allows contractors to pre-install coupling components, making final connections easier in confined areas. This configuration also provides superior concrete tight sealing, preventing infiltration during concrete pours that could compromise the electrical system integrity.

Why Choose Malleable Iron Construction?

Malleable iron provides exceptional strength and durability compared to standard steel fittings, making it the preferred choice for demanding electrical installations. This material offers superior impact resistance, better threading characteristics, and enhanced corrosion resistance. Backed by Eaton Crouse-Hinds' century of electrical innovation, this coupling delivers the professional-grade performance that electrical contractors trust for critical infrastructure projects.
