Eaton Crouse-Hinds 3" EMT Raintight Compression Coupling, Steel

Weather-Sealed Protection for Large Conduit Systems

The Eaton Crouse-Hinds 3" EMT Raintight Compression Coupling is a professional-grade conduit fitting engineered for weather-exposed electrical installations. This zinc-plated steel coupling delivers superior moisture protection and reliable conduit connections for commercial and industrial EMT systems requiring raintight performance.

Key Features & Benefits

Weather Protection Excellence

  • Raintight Design - Engineered sealing system prevents moisture infiltration in outdoor installations
  • Compression Connection - Creates secure, weather-sealed joints between EMT conduit sections
  • Corrosion-Resistant Finish - Zinc-plated steel construction withstands harsh environmental conditions
  • Professional Sealing - Integrated gasket system ensures long-term weather protection

Installation Efficiency

  • Compression Technology - No threading required, reducing installation time and labor costs
  • Precise Fit - Engineered specifically for 3" EMT conduit systems
  • Contractor-Friendly Design - Straightforward installation process for field technicians
  • Reliable Grounding - Maintains electrical continuity through the conduit system

Professional-Grade Construction

  • Heavy-Duty Steel - Superior strength and durability for demanding applications
  • Precision Manufacturing - Consistent dimensional accuracy ensures proper fit every time
  • Code Compliance - Meets NEC/CEC requirements for raintight conduit fittings
  • Quality Assurance - Backed by Eaton Crouse-Hinds' century of electrical innovation

Technical Specifications

This compression coupling accommodates 3" trade size EMT conduit with steel construction and zinc-plated finish for corrosion resistance. The raintight design meets stringent weather protection standards for outdoor and wet location installations. Dimensions measure 5.7" length x 4.4" width x 6.4" height with a weight of 2.45 pounds, providing substantial construction for reliable long-term performance. The coupling is designed for ordinary/non-hazardous locations and complies with NEC/CEC standards for professional electrical installations.

Installation Process

  1. Verify conduit ends are cut square and deburred for proper sealing
  2. Slide compression nuts onto both EMT conduit sections before assembly
  3. Insert conduit ends into coupling body until they meet internal stop
  4. Position gaskets properly to ensure raintight seal integrity
  5. Thread compression nuts onto coupling body finger-tight initially
  6. Tighten compression nuts with appropriate wrench to manufacturer specifications
  7. Verify secure connection and proper gasket compression for weather seal

Applications

Perfect for:

  • Outdoor Electrical Systems - Rooftop equipment connections, exterior lighting circuits
  • Industrial Facilities - Manufacturing plants, processing equipment, heavy machinery connections
  • Commercial Buildings - HVAC systems, exterior signage, parking lot lighting
  • Municipal Infrastructure - Street lighting, traffic control systems, public facility wiring
  • Agricultural Applications - Barn wiring, irrigation control systems, outdoor equipment
  • Wet Location Installations - Car washes, food processing facilities, marine environments
  • Large Conduit Systems - Main distribution runs, feeder circuits, high-capacity wiring
  • Equipment Connections - Motor control centers, switchgear, large electrical panels

Compression Coupling System Benefits

Compression couplings offer significant advantages over threaded alternatives, particularly in weather-exposed applications. The compression design creates a more reliable seal against moisture infiltration while eliminating the need for field threading. This reduces installation time, minimizes the risk of damaged threads, and provides consistent sealing performance. The integrated gasket system ensures long-term weather protection that maintains integrity through thermal cycling and environmental stress.

Why Choose Raintight Protection?

Raintight compression couplings are essential for maintaining electrical system integrity in outdoor and wet location installations. This Eaton Crouse-Hinds coupling combines professional-grade steel construction with precision-engineered sealing technology to prevent moisture-related failures. The robust design ensures decades of reliable service while meeting strict code requirements for weather protection, making it the preferred choice for electrical contractors who demand superior performance in challenging environments.
