Technical Specifications

This 4-inch trade size EMT compression coupling features zinc plated steel construction with precision-engineered compression mechanisms. The coupling accommodates standard 4-inch EMT conduit with secure mechanical connection that maintains grounding continuity throughout the conduit system. Designed for ordinary/non-hazardous locations with NEC/CEC compliance, this coupling measures 6.5 inches in height, 5.7 inches in length, and 5.4 inches in width, with a total weight of 4.85 pounds for substantial durability in heavy-duty applications.

Installation Process

1. Verify conduit ends are cut square and deburred to ensure proper seating
2. Slide compression nuts onto both conduit ends before positioning coupling
3. Insert conduit ends fully into coupling body until they meet internal stop
4. Position compression rings over conduit ends within coupling body
5. Thread compression nuts onto coupling body hand-tight initially
6. Use appropriate compression tools to tighten nuts to manufacturer specifications
7. Verify secure connection by checking for any movement between conduit and coupling
8. Test grounding continuity across the completed joint

• Warehouse Distribution - Large-scale storage and logistics facility power systems
• Equipment Connections - Motor control centers, switchgear, and distribution panel feeds

EMT Compression Coupling System Benefits

EMT compression couplings provide superior connection reliability compared to set screw alternatives, especially in applications subject to vibration or thermal cycling. The compression design creates a 360-degree contact surface that maintains consistent electrical continuity and mechanical strength over time. This is particularly important in 4-inch conduit systems that typically carry high-amperage circuits or multiple circuit bundles where connection integrity is critical for both safety and system performance.

Why Choose Zinc Plated Steel Construction?

Zinc plated steel offers the ideal balance of strength, corrosion resistance, and cost-effectiveness for EMT coupling applications. The zinc coating provides galvanic protection that prevents rust formation even when the coating is scratched, while the steel base material delivers the mechanical strength required for large conduit systems. This combination ensures reliable performance in both indoor and outdoor installations, making it the preferred choice of electrical contractors for commercial and industrial projects where long-term reliability is essential.
