Eaton Crouse-Hinds NPL50300SA conduit nipple - NEC/CEC
Part Number: NPL50300SA
Quick Summary
NPL50300SA conduit nipple by Eaton Crouse-Hinds provides a rugged aluminum rigid/IMC connection for wiring runs in industrial enclosures, delivering reliable mechanical continuity. Engineers often struggle with corrosion resistance, misfit fittings, and costly installation delays when routing conduits through compact panels and crowded junctions. The product supports NEC/CEC compliance for ordinary/non-hazardous locations, and Canadian certification references through UL documentation help streamline cross‑region projects. With a 1/2 in x 3 in size, aluminum body, and lightweight 0.07 lb mass, it reduces labor time and simplifies stocking, routing, and field installation in control cabinets. This combination of form factor and certified performance makes it a practical, cost-conscious choice for panel builders and OEMs.

Eaton Specification Sheet - NPL50300SA
The NPL50300SA is molded from aluminum and sized 1/2 in x 3 in, providing a rigid/IMC conduit nipple that blends strength with lightweight handling. This material choice yields corrosion resistance and easier handling on the job site, reducing fatigue during long pulls and inventory weight. Use in control panels, electrical cabinets, and industrial enclosures where space is tight and reliability matters. The 3 inch length minimizes joints in conduit runs, which lowers installation time and reduces potential leak points in critical circuits. Fewer components also translate to lower field labor and streamlined commissioning in medium and large panel builds. NEC/CEC compliance with ordinary/non-hazardous locations and available Canadian certification references help supersede multi-region regulatory hurdles, while the compact aluminum profile integrates smoothly with CH locknuts, washers, reducers, and plugs for ready-to-install assemblies.

FAQs
NPL50300SA is designed for 1/2 in Rigid/IMC conduits with a 3 in length and aluminum body, ensuring compatibility with common CH locknuts, washers, reducers, and plugs. For best results, align the conduit nipple with the mounting surface, secure with an appropriate locknut, and complete the run using standard CH accessories to maintain code compliance and a tight seal.
Key specs include conduit type: Rigid/IMC; material: aluminum; size: 1/2 in; length: 3 in; width: 0.84 in; height: 0.84 in; weight: 0.07 lb. These dimensions support compact routing and easy inventory management while delivering reliable mechanical integrity for general purpose installations.
Yes. The product is rated for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards. This makes it appropriate for general industrial facilities, commercial equipment, and OEM builds where non-hazardous indoor wiring runs are common, simplifying qualification and regulatory paperwork.
NEC/CEC compliance covers US and Canada installations, with Canadian certification references available in UL documentation for Conduit Fittings. This enables multi-region deployments with consolidated purchasing and simpler approvals during design reviews and site acceptances.
The 3 in length minimizes joints, while the lightweight 0.07 lb aluminum construction lowers handling and shipping costs. Its compatibility with standard CH accessories streamlines assemblies, reduces field labor, and accelerates commissioning in control panels and equipment cabinets.
