Eaton Crouse-Hinds 3/4" EMT Compression Coupling, Zinc Plated Steel

Professional-Grade Conduit Connection for Reliable Electrical Systems

The Eaton Crouse-Hinds 3/4" EMT Compression Coupling is a professional-grade conduit fitting engineered for secure EMT conduit connections in commercial and industrial electrical installations. This zinc plated steel compression coupling delivers superior corrosion resistance and reliable mechanical connection for demanding electrical applications.

Key Features & Benefits

Superior Corrosion Protection

  • Zinc Plated Steel Construction - Provides exceptional corrosion resistance for long-term durability in harsh environments
  • Weather-Resistant Finish - Protects against moisture, humidity, and environmental contaminants
  • Extended Service Life - Engineered for decades of reliable performance in commercial installations
  • Cost-Effective Protection - Superior material choice balances performance with value

Professional Installation Advantages

  • Compression Connection Design - Ensures secure, vibration-resistant conduit joints without threading
  • Quick Installation Process - Reduces labor time compared to threaded connections
  • Consistent Compression Force - Precision-engineered for uniform connection strength
  • No Special Tools Required - Standard wrenches provide proper installation torque

Code Compliance & Safety

  • NEC/CEC Compliant Design - Meets all applicable electrical code requirements
  • Ordinary Location Rated - Approved for standard commercial and industrial environments
  • Reliable Grounding Continuity - Maintains electrical continuity throughout conduit system
  • Professional Grade Quality - Trusted by electrical contractors for over 100 years

Technical Specifications

This 3/4" trade size EMT compression coupling features zinc plated steel construction with precision-machined threads and compression mechanism. The coupling measures 1.75" in length with a 1.38" diameter profile, weighing 0.18 pounds for easy handling during installation. Designed specifically for EMT (Electrical Metallic Tubing) applications, this coupling provides secure mechanical and electrical connection between conduit sections while maintaining NEC/CEC compliance for ordinary location installations.

Installation Process

  1. Ensure EMT conduit ends are cut square and deburred for proper seating
  2. Slide coupling over first conduit section until conduit reaches internal stop
  3. Insert second conduit section into opposite end until it reaches internal stop
  4. Hand-tighten compression nuts to secure initial connection
  5. Use appropriate wrenches to achieve final compression torque per manufacturer specifications
  6. Verify secure mechanical connection and proper conduit alignment

Applications

Perfect for:

  • Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
  • Industrial Facilities - Manufacturing plants, processing facilities, and distribution centers
  • Conduit Extensions - Joining EMT sections for longer conduit runs
  • Equipment Connections - Motor control centers, switchgear, and electrical panels
  • Renovation Projects - Extending existing EMT conduit systems
  • Municipal Infrastructure - Government buildings, schools, and public facilities
  • Maintenance Applications - Repairing damaged conduit sections
  • Branch Circuit Wiring - Power distribution and lighting circuits

EMT Compression Coupling System Benefits

EMT compression couplings provide superior connection reliability compared to set screw alternatives by creating uniform compression around the entire conduit circumference. This design eliminates potential weak points and ensures consistent grounding continuity throughout the electrical system. The compression mechanism also accommodates slight conduit variations while maintaining secure mechanical connection, making it ideal for professional installations where reliability is paramount.

Why Choose Zinc Plated Steel Construction?

Zinc plated steel offers the optimal balance of strength, corrosion resistance, and cost-effectiveness for EMT compression couplings. The zinc plating provides excellent protection against moisture and environmental contaminants while maintaining the structural integrity of steel construction. This material choice ensures long-term reliability in demanding commercial and industrial environments, backed by Eaton Crouse-Hinds' century of electrical innovation and professional-grade manufacturing standards.
