Technical Specifications

This coupling features a 3/4" trade size designed specifically for EMT (Electrical Metallic Tubing) applications. The zinc plated steel construction provides superior corrosion resistance compared to standard steel fittings, making it ideal for environments where moisture or humidity may be present. The coupling measures 1.88" in length with a 1.13" width and height profile, weighing just 0.16 pounds for easy handling during installation. The set screw connection type ensures secure mechanical and electrical connections that comply with NEC/CEC standards for ordinary/non-hazardous locations.

Installation Process

1. Ensure EMT conduit ends are cut square and deburred to prevent damage to coupling threads
2. Insert first EMT conduit section into one end of the coupling until it reaches the internal stop
3. Tighten the set screws on the first end using appropriate screwdriver to secure the conduit
4. Insert second EMT conduit section into the opposite end until it reaches the internal stop
5. Tighten the set screws on the second end to complete the mechanical and electrical connection
6. Verify both conduit sections are securely fastened and properly aligned for system continuity

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail stores, restaurants, and hospitality facilities
• Industrial Facilities - Manufacturing plants, warehouses, and processing facilities
• Institutional Projects - Schools, hospitals, government buildings, and municipal facilities
• EMT System Extensions - Connecting conduit runs in new construction and renovation projects
• Equipment Connections - Linking conduit systems to electrical panels, motor control centers, and distribution equipment
• Interior Installations - Dry location applications where corrosion resistance is still desired
• Maintenance Applications - Conduit repairs and system modifications in existing electrical installations
• Multi-Level Buildings - Vertical and horizontal conduit runs requiring secure intermediate connections

EMT Coupling System Benefits

EMT set screw couplings provide superior connection reliability compared to compression-only fittings by creating both mechanical grip and electrical continuity through the set screw contact points. This dual-action connection method ensures that conduit systems maintain their integrity even under thermal expansion, vibration, or minor structural movement. The set screw design also allows for easier disassembly during maintenance or system modifications, making it the preferred choice for professional electrical contractors.

Why Choose Zinc Plated Steel?

Zinc plated steel construction offers the perfect balance of strength, corrosion resistance, and cost-effectiveness for EMT coupling applications. The zinc plating provides a protective barrier against moisture and oxidation while maintaining the structural strength of steel. This makes it ideal for installations where aluminum might be too soft and stainless steel would be unnecessarily expensive, delivering professional-grade performance that electrical contractors can depend on for long-term system reliability.
