• Corrosion-Resistant Steel - Zinc-plated finish provides long-term protection against rust and environmental degradation
• NEMA Compliant Sealing - Meets stringent standards for moisture protection in electrical systems

Professional Installation Advantages

• Compression Connection - No threading required, reducing installation time and labor costs
• Secure Conduit Grip - Compression mechanism ensures permanent, vibration-resistant connection
• Electrical Continuity - Steel construction maintains reliable grounding path throughout conduit system
• Precision Tolerances - Engineered fit eliminates gaps and ensures consistent seal performance

Durability & Reliability

• Heavy-Duty Steel Construction - Superior strength compared to aluminum alternatives for demanding applications
• Impact Resistance - Withstands mechanical stress from thermal expansion and building movement
• Long Service Life - Engineered for decades of maintenance-free operation in harsh environments

Technical Specifications

This 3/4" trade size compression coupling accommodates standard EMT conduit with steel construction and zinc-plated finish. The coupling measures 3.06" in length, 1.31" in width, and 1.06" in height, weighing 0.21 pounds for easy handling during installation. Designed for ordinary/non-hazardous locations with NEC/CEC compliance, this raintight coupling provides reliable performance in wet location applications where moisture protection is critical.

Installation Process

1. Verify conduit ends are cut square and deburred to prevent damage to compression seals
2. Slide coupling onto first EMT conduit section, ensuring full insertion to internal stop
3. Insert second conduit section into opposite end of coupling to internal stop
4. Tighten compression nuts using appropriate wrenches, alternating sides for even pressure
5. Verify secure connection by attempting to pull conduit sections apart
6. Test raintight seal integrity before energizing electrical system

Applications

Perfect for:

• Outdoor Electrical Systems - Parking lot lighting, exterior building power, landscape electrical
• Industrial Facilities - Manufacturing plants, processing facilities, warehouse electrical distribution
• Commercial Buildings - Rooftop HVAC connections, exterior signage, building perimeter lighting
• Municipal Infrastructure - Street lighting, traffic signals, public facility electrical systems
• Agricultural Applications - Barn electrical, irrigation controls, outdoor equipment connections
• Marine Environments - Dock electrical, boat lift controls, waterfront facility power
• Wet Location Requirements - Car wash facilities, food processing plants, chemical processing areas
• Conduit Extensions - Joining EMT runs in weather-exposed installations

EMT Compression Coupling System Benefits

Compression couplings offer significant advantages over threaded connections in EMT systems, particularly in wet locations. The compression design eliminates the need for threading conduit ends, reducing installation time and preventing thread damage that can compromise seal integrity. The mechanical compression creates a more reliable seal than threaded connections, especially important in applications subject to thermal cycling and vibration.

Why Choose Raintight Protection?

Moisture infiltration is one of the leading causes of electrical system failure and safety hazards. This Eaton Crouse-Hinds raintight compression coupling provides essential protection against water ingress, preventing conductor corrosion, insulation breakdown, and dangerous fault conditions. The steel construction ensures long-term durability while maintaining electrical continuity throughout the conduit system, making it the preferred choice for electrical contractors working in challenging environmental conditions.
