Technical Specifications

This conduit bushed nipple features 4" trade size threading compatible with rigid steel and IMC conduit systems. The zinc die cast construction provides superior corrosion resistance while maintaining the non-insulated design required for proper electrical grounding continuity. Product dimensions are 5.4" length x 4.5" width x 1.94" height with a weight of 0.7 pounds. The fitting is designed for ordinary/non-hazardous locations and complies with NEC/CEC electrical code standards for professional electrical installations.

Installation Process

1. Verify conduit ends are properly reamed and deburred to prevent conductor damage
2. Apply appropriate thread compound to male threads for weather-resistant seal
3. Thread nipple hand-tight into first conduit or fitting connection
4. Use appropriate conduit wrenches to achieve final tight connection without over-torquing
5. Install second conduit section, ensuring proper alignment and full thread engagement
6. Verify electrical continuity through the complete conduit run for proper grounding

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
• Electrical Distribution Systems - Main distribution panels, sub-panels, and switchgear connections
• Equipment Connections - Motor control centers, transformers, and large electrical equipment
• Conduit Extensions - Extending conduit runs through walls, floors, and structural barriers
• Chase Installations - Running conduit through concrete walls, masonry, and structural chases
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
• High-Capacity Circuits - Large conductor installations requiring 4" conduit systems

Conduit Bushed Nipple System Benefits

Conduit bushed nipples provide essential flexibility in electrical conduit routing while maintaining system integrity. Unlike standard nipples, the bushed design features smooth interior surfaces that protect conductor insulation during installation and service. This is particularly critical in 4" systems where multiple large conductors must be pulled through the fitting. The threaded design provides superior mechanical strength compared to compression fittings while ensuring reliable electrical continuity for proper system grounding.

Why Choose Zinc Die Cast Construction?

Zinc die cast construction offers significant advantages over traditional steel fittings in demanding electrical applications. The precision casting process ensures consistent dimensions and superior thread quality, reducing installation time and improving long-term reliability. The inherent corrosion resistance of zinc die cast material provides extended service life in challenging environments while maintaining the electrical properties required for proper system grounding. For electrical contractors working on high-value commercial and industrial projects, the superior quality and reliability of Eaton Crouse-Hinds zinc die cast fittings justify the investment through reduced callbacks and enhanced system performance.
