Technical Specifications

This 1-inch trade size compression coupling is manufactured from malleable iron for superior strength and durability. The coupling accommodates both rigid steel conduit and intermediate metal conduit (IMC) systems. With compact dimensions of 2.19 inches length, 2 inches width, and 2 inches height, this fitting weighs 0.59 pounds and provides reliable connections in ordinary/non-hazardous locations. The compression-type connection mechanism ensures secure attachment without requiring threaded connections.

Installation Process

1. Verify conduit ends are cut square and deburred to prevent damage to coupling threads
2. Insert first conduit section into one end of the compression coupling until fully seated
3. Tighten compression fitting on first conduit end to manufacturer specifications
4. Insert second conduit section into opposite end of coupling until properly positioned
5. Secure second compression connection, ensuring both conduits are properly aligned
6. Verify mechanical integrity and grounding continuity of completed connection

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial applications
• Equipment Connections - Motor control centers, switchgear, and electrical distribution panels
• Conduit Extensions - Joining conduit runs where threading is impractical or impossible
• Repair Applications - Replacing damaged conduit sections without extensive rework
• Municipal Infrastructure - Schools, government buildings, and public facilities
• Maintenance Projects - Electrical system modifications and upgrades
• New Construction - Primary electrical distribution systems requiring reliable connections

Compression Coupling System Benefits

Compression couplings offer significant advantages over traditional threaded connections by eliminating the need for field threading while providing superior mechanical strength. The compression design creates a secure connection that maintains grounding continuity and prevents conduit separation under mechanical stress. This makes compression couplings ideal for applications where vibration, thermal expansion, or structural movement could compromise threaded connections.
