Technical Specifications

This 4" trade size EMT compression coupling features zinc-plated steel construction with raintight sealing capabilities. The coupling measures 6.7" in height, 5.7" in length, and 5.4" in width, with a total weight of 4.85 pounds. Designed specifically for EMT conduit systems, it meets NEC/CEC compliance standards for ordinary/non-hazardous locations and provides reliable connections for large electrical distribution systems.

Installation Process

1. Verify EMT conduit ends are cut square and deburred for proper sealing
2. Insert first EMT section into coupling until it reaches the internal stop
3. Position coupling at desired location and insert second EMT section
4. Tighten compression nuts evenly using appropriate wrenches to manufacturer specifications
5. Verify both conduit sections are fully seated and compression seals are properly engaged
6. Test connection integrity and confirm raintight seal before energizing system

Applications

Perfect for:

• Outdoor Electrical Systems - Rooftop equipment connections, exterior lighting circuits, and weather-exposed installations
• Commercial Buildings - Large office complexes, retail centers, and institutional facilities requiring weather protection
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy-duty electrical distribution systems
• Municipal Infrastructure - Schools, government buildings, and public facilities with exterior electrical systems
• Equipment Connections - HVAC units, outdoor electrical panels, and rooftop mechanical equipment
• Parking Structures - Covered parking areas, garages, and semi-exposed electrical installations
• Agricultural Systems - Barn electrical systems, irrigation controls, and farm equipment connections
• Conduit Extensions - Joining EMT runs in wet locations and weather-exposed conduit systems

EMT Compression Coupling System Benefits

EMT compression couplings provide superior installation flexibility compared to threaded alternatives, eliminating the need for field threading while delivering reliable connections. The compression design creates consistent, weather-sealed joints that maintain electrical continuity and protect against moisture infiltration. This makes them ideal for applications where conduit runs must traverse weather-exposed areas or connect equipment in wet locations.

Why Choose Raintight Protection?

Raintight compression couplings are essential for electrical systems exposed to weather conditions, providing the moisture protection required by electrical codes for wet location installations. The Eaton Crouse-Hinds design combines proven sealing technology with professional-grade construction, ensuring long-term reliability in demanding outdoor environments while maintaining the installation efficiency that electrical contractors depend on for productive job completion.
