Eaton Crouse-Hinds 1-1/2" EMT Compression Coupling, Zinc Plated Steel

Professional-Grade Conduit Connection for Reliable EMT Systems

The Eaton Crouse-Hinds 1-1/2" EMT Compression Coupling is a professional-grade conduit fitting engineered for secure, permanent connections in electrical metallic tubing systems. This zinc plated steel coupling delivers superior corrosion resistance and mechanical strength for commercial and industrial electrical installations where reliability is critical.

Key Features & Benefits

Superior Compression Connection

  • Compression-type design - Creates secure, vibration-resistant connections that won't loosen over time
  • 360-degree compression - Ensures uniform grip around entire conduit circumference for maximum holding power
  • No threading required - Faster installation compared to threaded couplings, reducing labor costs
  • Permanent connection - Once installed, provides decades of reliable service without maintenance

Corrosion Protection & Durability

  • Zinc plated steel construction - Superior corrosion resistance for indoor and outdoor applications
  • Professional-grade materials - Engineered to withstand harsh industrial environments and temperature cycling
  • Impact resistant design - Maintains connection integrity even under mechanical stress
  • Long-term reliability - Trusted by electrical contractors for over 100 years of proven performance

Code Compliance & Safety

  • NEC/CEC compliant - Meets all National Electrical Code and Canadian Electrical Code requirements
  • Grounding continuity - Maintains electrical continuity through the conduit system for proper grounding
  • Ordinary location rated - Suitable for standard commercial and industrial electrical installations

Technical Specifications

This 1-1/2 inch trade size EMT compression coupling features zinc plated steel construction with compression-type connection mechanism. The coupling measures 2.25 inches in length, width, and height, with a total weight of 0.63 pounds. Designed specifically for electrical metallic tubing (EMT) applications, it provides reliable conduit-to-conduit connections in ordinary/non-hazardous locations while maintaining full NEC/CEC compliance for professional electrical installations.

Installation Process

  1. Ensure EMT conduit ends are cut square and deburred to prevent damage to coupling threads
  2. Slide coupling onto first conduit end until conduit bottoms out in coupling interior
  3. Insert second conduit end into opposite side of coupling until it bottoms out
  4. Tighten compression nuts using appropriate wrenches, alternating between sides for even compression
  5. Verify secure connection by attempting to pull conduits apart - properly installed coupling will not separate
  6. Check that coupling maintains proper alignment between conduit runs for smooth wire pulling

Applications

Perfect for:

  • Commercial Buildings - Office complexes, retail stores, hospitals, and educational facilities
  • Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
  • Equipment Connections - Motor control centers, switchgear, and electrical distribution panels
  • Conduit Extensions - Joining EMT runs where longer continuous lengths are required
  • Repair Applications - Replacing damaged conduit sections without rewiring entire runs
  • Outdoor Installations - Weather-exposed applications where corrosion resistance is critical
  • Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
  • Agricultural Systems - Barn and facility wiring where durability and corrosion resistance are essential

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 eliminates potential weak points and ensures consistent grounding continuity throughout the electrical system. The compression design also accommodates slight conduit variations while maintaining secure connections that won't loosen due to vibration or thermal cycling.

Why Choose Zinc Plated Steel Construction?

Zinc plated steel offers the ideal combination of strength, durability, and corrosion protection for professional EMT installations. The zinc coating provides excellent corrosion resistance while the steel core delivers superior mechanical strength compared to aluminum alternatives. This construction ensures decades of reliable service in both indoor and outdoor applications, making it the preferred choice of electrical contractors for mission-critical installations where failure is not an option.
