Technical Specifications

This 4" trade size coupling features malleable iron construction with concrete tight sealing capabilities. The three-piece design accommodates rigid steel and IMC conduit systems while maintaining NEC/CEC compliance standards. Product dimensions measure 5.8" length x 5.6" width x 7.7" height with an 8-pound weight that reflects the substantial malleable iron construction. The coupling is rated for ordinary/non-hazardous locations and provides reliable performance in commercial and industrial electrical installations.

Installation Process

1. Verify conduit ends are properly cut, deburred, and threaded to standard specifications
2. Apply appropriate thread compound to conduit threads for weather-tight seal
3. Thread the first coupling piece onto the first conduit run, ensuring full thread engagement
4. Position the center coupling body and align with both conduit runs
5. Thread the second coupling piece onto the opposite conduit run
6. Tighten all connections to manufacturer specifications using appropriate wrenches
7. Verify grounding continuity and proper mechanical connection before concrete pour operations

Applications

Perfect for:

• Commercial Construction - Office buildings, retail centers, hospitals, and educational facilities
• Industrial Installations - Manufacturing plants, processing facilities, and heavy industrial applications
• Concrete Pour Applications - Underground conduit runs, foundation installations, and slab-on-grade construction
• Municipal Infrastructure - Government buildings, public utilities, and civic construction projects
• Heavy-Duty Electrical Systems - Large conduit runs requiring 4" capacity for multiple circuit installations
• Equipment Connections - Motor control centers, switchgear, and electrical distribution equipment
• Conduit Extensions - Field modifications and system expansions requiring reliable connections
• Maintenance Applications - Conduit repairs and system upgrades in existing installations

Three-Piece Coupling System Benefits

Three-piece conduit couplings offer significant advantages over traditional two-piece designs, particularly in construction and maintenance applications. The segmented design allows installation without removing or repositioning existing conduit runs, saving substantial labor time and reducing project complexity. This flexibility is especially valuable in concrete pour applications where conduit positioning cannot be easily adjusted once forms are in place.

Why Choose Malleable Iron Construction?

Malleable iron provides superior strength and durability compared to standard steel alternatives, making it the preferred choice for heavy-duty electrical applications. This material offers excellent impact resistance, superior threading characteristics, and enhanced corrosion resistance when properly finished. For 4" conduit systems carrying multiple circuits or serving critical electrical loads, malleable iron construction ensures decades of reliable service with minimal maintenance requirements, making it the smart choice for professional electrical contractors.
