Technical Specifications

This 1-1/2" trade size coupling features malleable iron construction with concrete tight sealing capabilities. The three-piece design measures 2.81" in height and width with a 2.38" depth, weighing 1.67 pounds for substantial durability. Compatible with both rigid steel conduit and intermediate metal conduit (IMC) systems, it provides secure connections in ordinary/non-hazardous locations while maintaining NEC/CEC compliance standards.

Installation Process

1. Verify conduit ends are properly reamed and deburred for smooth wire pulling
2. Apply approved pipe thread compound to male conduit threads
3. Thread first conduit section into coupling body hand-tight plus 1-2 turns
4. Align second conduit section and thread into opposite end of coupling
5. Tighten both connections using appropriate wrenches, ensuring proper alignment
6. Verify coupling is concrete tight if installation involves concrete pour operations

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy equipment installations
• Concrete Pour Applications - Underground conduit runs, foundation installations, and slab-on-grade systems
• Equipment Connections - Motor control centers, switchgear, and distribution panel feeds
• Conduit Extensions - Joining conduit sections in long runs and complex routing situations
• Renovation Projects - Connecting new conduit to existing rigid/IMC systems
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
• Heavy-Duty Applications - High-vibration environments requiring maximum connection strength

Three-Piece Coupling System Benefits

Three-piece couplings offer significant advantages over standard two-piece designs, particularly in challenging installation conditions. The separable construction allows electricians to make connections in tight spaces where rotating long conduit sections would be impossible. This design also enables precise alignment corrections and simplifies installation in concrete pour applications where the coupling must remain stationary while conduit sections are positioned.

Why Choose Malleable Iron Construction?

Malleable iron provides superior strength compared to standard steel fittings, with exceptional resistance to impact and thermal stress. This material choice ensures the coupling maintains structural integrity under heavy loads, temperature cycling, and mechanical stress. The concrete tight design prevents infiltration during pour operations, eliminating costly rework and maintaining long-term system reliability in demanding commercial and industrial electrical installations.
