Eaton Crouse-Hinds 1-1/2" Rigid/IMC Conduit Bushed Nipple, Malleable Iron

Heavy-Duty Chase Nipple for Professional Electrical Installations

The Eaton Crouse-Hinds 1-1/2" Rigid/IMC Conduit Bushed Nipple is a professional-grade chase nipple engineered for secure conduit-to-enclosure connections. This malleable iron fitting delivers superior strength and durability for commercial and industrial electrical installations requiring reliable conduit transitions.

Key Features & Benefits

Superior Material Construction

• Malleable Iron Construction - Stronger than steel with exceptional impact resistance and dimensional stability
• Non-Insulated Design - Maintains electrical continuity and grounding path throughout the conduit system
• Precision Threading - Machine-cut threads ensure secure, leak-resistant connections to enclosures and conduit
• Corrosion Resistant Finish - Factory applied coating protects against environmental degradation

Professional Installation Advantages

• Bushed Design - Smooth interior protects wire insulation during installation and maintenance
• Standard Trade Size - 1-1/2" sizing ensures compatibility with standard rigid and IMC conduit systems
• Compact Profile - 2.31" length provides secure connection without excessive enclosure penetration
• Lightweight Construction - 0.3 lb weight reduces installation fatigue while maintaining structural integrity

Technical Specifications

This 1-1/2" trade size conduit bushed nipple features malleable iron construction with non-insulated throat design for optimal grounding continuity. The fitting measures 2.31" in length with 1.13" height, providing secure penetration depth for panel and enclosure connections. Compatible with both rigid steel and intermediate metal conduit (IMC) systems, this nipple meets NEC/CEC compliance standards for ordinary/non-hazardous locations. The precision-threaded design ensures proper engagement with standard electrical enclosures and conduit fittings.

Installation Process

1. Verify enclosure knockout size matches 1-1/2" trade size requirements
2. Thread nipple through enclosure wall from interior, ensuring bushed end faces wire entry direction
3. Secure nipple to enclosure using appropriate locknut, tightening to manufacturer specifications
4. Thread rigid or IMC conduit onto exterior nipple threads, ensuring full engagement
5. Install conduit locknut and tighten to secure mechanical connection
6. Verify grounding continuity through non-insulated connection path

Applications

Perfect for:

• Panel Board Connections - Main electrical panels, sub-panels, and distribution boards
• Motor Control Centers - Industrial motor starter and control panel connections
• Switchgear Applications - High-voltage switching equipment and transformer connections
• Junction Box Transitions - Large pull boxes and splice enclosures in commercial systems
• Equipment Connections - HVAC units, pumps, and industrial machinery electrical feeds
• Outdoor Enclosures - Weather-resistant electrical cabinets and control stations
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial applications
• Commercial Buildings - Office complexes, retail centers, and institutional facilities

Conduit Bushed Nipple System Benefits

Conduit bushed nipples provide superior wire protection compared to standard nipples by incorporating smooth, rounded interior surfaces that eliminate sharp edges. This design significantly reduces the risk of wire insulation damage during installation and system modifications. The bushed configuration also facilitates easier wire pulling in high-conductor-count applications, reducing installation time and labor costs while ensuring long-term system reliability.

Why Choose Malleable Iron Construction?

Malleable iron offers exceptional advantages over standard steel fittings, providing superior impact resistance and dimensional stability under mechanical stress. This material choice ensures reliable performance in demanding industrial environments where vibration, thermal cycling, and mechanical loads are common. The non-insulated design maintains critical grounding continuity throughout the electrical system, meeting NEC requirements while providing the robust construction that electrical professionals have trusted for over 100 years.
