Eaton Crouse-Hinds NPL400600SA conduit nipple NEC/CEC
Part Number: NPL400600SA
Quick Summary
Eaton Crouse-Hinds NPL conduit nipple provides rugged conduit joining for rigid/IMC systems in industrial installations. Installers often struggle with corrosion, misalignment, and grounding continuity in harsh environments, which can slow projects and raise warranty concerns. This product is NEC/CEC compliant and rated for Ordinary/Non-Hazardous locations, with UL certification for Canada, delivering cross-border confidence. By combining aluminum construction with precise dimensions for a 4x6 inch face and a 6 inch length, it reduces weight without sacrificing strength. The result is faster, safer installations, fewer field adjustments, and improved long-term reliability for panel feed-throughs and equipment enclosures—supporting efficiency, compliance, and total cost of ownership improvements across the facility.

Material and corrosion resistance: Constructed from aluminum, the NPL400600SA delivers strong corrosion resistance in demanding environments while remaining lighter than steel equivalents. This reduces on-site fatigue, simplifies handling, and lowers labor costs during installation. Application: ideal for outdoor enclosures or wash-down areas where aluminum fittings can be advantageous. Conduit type compatibility: Designed for rigid/IMC systems, this nipple integrates with standard conduit fittings and locknuts in the Crouse-Hinds line. Business impact: ensures a tight, grounded connection that maintains electrical continuity and reduces rework. Application: suitable for control panels, motor starters, and industrial enclosures in NA facilities. Dimensions and fit: With a 4" x 6" size and 6" length, this nipple fits typical panel knockouts and enclosure assemblies. Business impact: predictable install times and fewer field modifications. Application: use in enclosures and conduits where space constraints require precise face dimensions. Compliance and standards: NEC/CEC compliant and rated for Ordinary/Non-Hazardous locations. Business impact: confidence for project approvals, safer installations, and easier regulatory audits. Application: North American facilities requiring NEC/CEC alignment with UL Canadian certification. Handling and installation efficiency: Weight 1.49 lb supports easier handling and fewer injuries during assembly. Business impact: faster commissioning, reduced labor hours, and improved site productivity. Application: field install across panels, machines, and equipment enclosures. Documentation and support: Access Eaton’s specification sheet and catalog pages for NPL400600SA, plus UL Canada certification references. Business impact: verified performance data and streamlined procurement.

FAQs
The NPL400600SA is designed for rigid/IMC conduit and fits standard Crouse-Hinds locknuts, washers, and fittings. Made from aluminum, it provides a secure, corrosion-resistant connection at a 4x6 face and 6 inch length suitable for panel feed-throughs. This compatibility minimizes the need for adapters and ensures reliable grounding and electrical continuity in demanding industrial environments.
NEC/CEC compliance is built into the NPL400600SA, and it is rated for Ordinary/Non-Hazardous Locations. This makes it suitable for most North American industrial facilities and commercial spaces while simplifying project approvals. For cross-border use, UL certification references demonstrate Canada compatibility; always verify local code interpretations and confirm that all accompanying locknuts and washers are installed per the specification sheet.
Aluminum construction yields corrosion resistance in harsh environments and lighter weight than steel, which translates to easier handling and reduced field fatigue. The NPL400600SA also resists impact and abrasion in typical industrial settings. Application: crew-safe installations in panels or enclosures where a stable, durable conduit nipple supports long service life and minimizes replacement costs.
Key measurements to consider include the 4x6 face and 6 in length, with overall dimensions 4.5 in width and height and a weight of 1.49 lb. Material is aluminum, and the area classification is Ordinary/Non-Hazardous. Ensure proper locknut installation and tighten to manufacturer torque specs to maintain grounding continuity and enclosure integrity during field installation.
Documentation supporting performance includes Eaton’s specification sheet for NPL400600SA and the Crouse-Hinds catalog page, plus UL Canada certification references. Access to these sources helps procurement teams verify material compatibility, dimensional accuracy, and compliance before purchase. Always cross-check the latest revision of the datasheet and ensure compatible accessories are listed in the installation manual.
