Technical Specifications

This 3/4" trade size compression coupling features malleable iron construction with dimensions of 1.88" length, 1.63" width, and 1.63" height, weighing 0.38 pounds. The coupling is designed specifically for rigid steel and IMC conduit applications in ordinary/non-hazardous locations. The compression-type connection method provides superior holding power while maintaining proper grounding continuity throughout the conduit system. NEC/CEC compliant construction ensures code compliance for professional electrical installations.

Installation Process

1. Verify conduit ends are cut square and deburred to prevent damage to coupling threads
2. Insert first conduit end into coupling until it reaches the internal stop
3. Tighten compression fitting using appropriate wrench size to manufacturer specifications
4. Insert second conduit end and repeat compression process for secure connection
5. Verify proper grounding continuity through the completed connection
6. Test connection security by applying gentle pressure to ensure no movement

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial applications
• Equipment Connections - Motor control centers, switchgear, and electrical distribution panels
• Conduit Extensions - Joining conduit runs where threading is impractical or impossible
• Renovation Projects - Connecting new conduit to existing systems without field threading
• Underground Applications - Concrete-tight installations where superior strength is required
• Vibration-Prone Areas - Locations where mechanical stress could loosen threaded connections
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems

Compression Coupling System Benefits

Compression couplings offer significant advantages over traditional threaded connections, particularly in applications where field threading is difficult or where superior holding power is required. The compression design creates a mechanical connection that resists loosening from vibration while maintaining excellent grounding continuity. This makes compression couplings ideal for industrial environments and applications where long-term reliability is critical.

Why Choose Malleable Iron Construction?

Malleable iron provides superior strength and durability compared to standard steel fittings, making it the preferred choice for demanding electrical applications. The material's exceptional tensile strength and impact resistance ensure reliable performance even under mechanical stress, while the precision manufacturing process guarantees consistent fit and finish. Backed by Eaton Crouse-Hinds' century of electrical innovation, this coupling represents the gold standard in professional conduit fittings.
