Eaton Crouse-Hinds NPL150400SA Conduit Nipple - NEC/CEC
Part Number: NPL150400SA
Quick Summary
NPL150400SA conduit nipple is a rugged aluminum connector for rigid/IMC installations in industrial wiring. Engineers often grapple with compatibility gaps and project-delays when sourcing reliable conduit fittings. This part meets NEC/CEC standards and UL certification, with Ordinary/Non-Hazardous area classification to support safe, compliant use in typical facility environments. By combining lightweight aluminum with precise 1-1/2 in diameter and 4 in length, it resists corrosion while maintaining strong mechanical strength. The fit simplifies field assembly and reduces maintenance cycles, translating to lower total cost of ownership. Use cases span machine enclosures, panel wiring, and process automation networks, reinforcing performance and reliability in demanding settings.
