• Concrete Tight Design - Prevents concrete infiltration during pour operations, eliminating costly rework
• Corrosion Resistant Finish - Long-lasting protection against environmental elements and chemical exposure
• Precision Threading - Ensures secure, leak-proof connections with consistent torque requirements

Professional Installation Advantages

• Three-Piece Design - Allows for easy alignment and adjustment during installation without conduit rotation
• Universal Compatibility - Works with both rigid steel and IMC conduit systems for maximum versatility
• Field Adjustable - Accommodates slight misalignments and thermal expansion in long conduit runs
• Grounding Continuity - Maintains electrical continuity throughout the conduit system per NEC requirements

Code Compliance & Safety

• NEC/CEC Compliant - Meets all National and Canadian Electrical Code requirements for conduit fittings
• Ordinary Location Rated - Suitable for standard commercial and industrial environments
• Professional Grade Quality - Engineered to exceed industry standards for long-term reliability

Technical Specifications

This 1" trade size three-piece conduit coupling features malleable iron construction with concrete tight sealing capabilities. The coupling measures 1.88" in width and height with a 1.63" depth, weighing 0.6 pounds for substantial durability. Compatible with both rigid steel and IMC conduit systems, this fitting maintains NEC/CEC compliance standards and provides reliable grounding continuity. The three-piece design allows for field adjustment and easy installation without requiring conduit rotation.

Installation Process

1. Verify conduit ends are cut square and deburred to prevent damage to coupling threads
2. Thread the first coupling piece onto the first conduit section hand-tight
3. Position the center coupling body and align with the second conduit section
4. Thread the third coupling piece onto the second conduit section
5. Tighten all connections using appropriate wrenches, ensuring proper torque without over-tightening
6. Verify grounding continuity and concrete tight seal integrity before concrete pour operations

Applications

Perfect for:

• Concrete Pour Applications - Underground electrical installations, foundation work, and slab-on-grade construction
• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy equipment installations
• Infrastructure Projects - Municipal buildings, transportation facilities, and utility installations
• Conduit Extensions - Joining conduit runs where standard lengths are insufficient
• Repair Applications - Replacing damaged conduit sections without complete system rewiring
• Expansion Joints - Accommodating thermal movement in long conduit runs
• Equipment Connections - Motor control centers, switchgear, and distribution panel connections

Three-Piece Coupling System Benefits

Three-piece conduit couplings offer significant advantages over standard two-piece designs by eliminating the need to rotate conduit sections during installation. This is particularly valuable when connecting to equipment or in tight spaces where conduit movement is restricted. The design also allows for precise alignment adjustments and accommodates slight dimensional variations in conduit runs, reducing installation time and improving system reliability.

Why Choose Malleable Iron Construction?

Malleable iron provides superior strength compared to standard steel fittings, with exceptional resistance to impact damage and thermal stress. This material choice ensures decades of reliable service in demanding electrical installations, while the concrete tight design prevents costly concrete infiltration during construction. Trusted by electrical professionals for over 100 years, Eaton Crouse-Hinds malleable iron fittings represent the gold standard for professional-grade electrical installations.
