Eaton Specification Sheet - NPL250500SA
Aluminum construction → Provides corrosion resistance and lighter weight, reducing damage risk and easing handling during installation. This translates to faster field assembly, lower freight costs, and longer service life in demanding environments. Application: Use NPL250500SA for 2-1/2 in rigid/IMC conduit runs in factory floors, processing lines, and outdoor equipment where exposure to moisture and salts is possible. Size and fit → Precise 2-1/2 in conduit size with a 5 in length delivers a clean, code-compliant connection that minimizes misalignment. Business impact: fewer call-backs and reworks, improved panel density, and consistent electrical clearances. Application: Ideal for control panels, machine housings, and enclosures that require a compact, reliable nipple between fittings. Conduit compatibility → Designed for Rigid/IMC conduit, ensuring robust mechanical integrity and predictable performance under vibration and thermal cycling. Business impact: reduces field failure risk and simplifies commissioning with standardized components. Application: Suitable for industrial machinery, process lines, and automation cabinets where a durable aluminum nipple is preferred. Area classification and standards → Rated for Ordinary/Non-Hazardous Locations and NEC/CEC standards support broad installation scope. Business impact: ensures regulatory alignment, easier procurement, and safer operations. Application: Implement in general purpose electrical installations across manufacturing plants and warehouses that require compliant conduit connections. Traceability and support → Catalog Number NPL250500SA enables precise procurement and fast replacement, backed by Eaton’s specification sheets and UL-Canada certification references. Business impact: reduces stocking SKUs, accelerates maintenance, and improves warranty coverage with documented compliance. Application: Integrate into BOMs for electrical installations and use Eaton’s resources for installation guidance.

FAQs
Yes. The NPL250500SA is specifically designed to mate with 2-1/2 in rigid/IMC conduit. To install, align the nipple with the conduit ends, ensure the mating threads are clean and undamaged, and use appropriate fittings and locknuts per the Eaton specification sheet. Verify the assembly fits within enclosure clearances and maintains proper grounding continuity during panel commissioning.
Key specs include a 5 inch product length, 2.88 inch height and width, 0.64 lb weight, aluminum material, catalog number NPL250500SA, UPC 662276484849, and compatibility with rigid/IMC conduit. The area classification is Ordinary/Non-Hazardous Locations, and NEC/CEC standards apply. These details support accurate BOM planning and compliant installations in general industrial environments.
NPL250500SA is rated for Ordinary/Non-Hazardous Locations. It should not be used in classified hazardous environments. For hazardous locations, select conduit nipples that carry the appropriate certifications and ratings for those specific conditions, and consult the manufacturer’s datasheets and local codes to ensure compliance.
The product adheres to NEC/CEC standards and is rated for ordinary locations, with Canadian certification options available through UL listings shown in Eaton’s resources. You can reference the Eaton specification sheet for NPL250500SA and UL Canada certification pages in the supporting downloads to confirm compliance and compatibility with your regulatory requirements.
Using the NPL250500SA can lower total cost of ownership by reducing field rework, speeding up installation, and improving long-term reliability due to corrosion resistance and robust aluminum construction. The standardized 2-1/2 in x 5 in rigid/IMC nipple also simplifies BOMs, procurement, and maintenance planning, delivering predictable project timelines and reduced downtime in manufacturing environments.
