Technical Specifications

This 3-inch trade size compression coupling features malleable iron construction for maximum strength and durability. Compatible with both rigid steel conduit and intermediate metal conduit (IMC) systems, it provides a secure compression connection without requiring threaded conduit ends. The coupling is designed for ordinary/non-hazardous locations and delivers reliable grounding continuity essential for electrical safety. Precision manufacturing ensures consistent fit and performance across installations.

Installation Process

1. Verify conduit ends are cut square and deburred for proper seating
2. Slide compression coupling onto first conduit end until fully seated
3. Insert second conduit end into opposite side of coupling
4. Tighten compression mechanism to manufacturer specifications
5. Verify secure connection and proper grounding continuity
6. Test connection integrity before energizing system

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial applications
• Power Distribution Systems - Main electrical panels, distribution boards, and switchgear connections
• Motor Control Centers - Equipment connections requiring large conduit sizes
• Municipal Infrastructure - Government buildings, schools, and public facility electrical systems
