Eaton Specification Sheet - NPL50CL 304SS
Material and corrosion resistance is a cornerstone of this conduit nipple; made from 304 stainless steel, it delivers prolonged service life in wet or corrosive environments, reducing replacement cycles and maintenance costs. This directly improves total cost of ownership for automation projects and panel builds while providing a robust option for outdoor enclosures and exposed installations where reliability matters. Rigid/IMC compatibility ensures a solid mechanical connection, resisting vibration and misalignment in fast-paced industrial settings and enabling quicker, cleaner installations with fewer field adjustments. By meeting NEC/CEC requirements for Ordinary/Non-Hazardous Locations, fabricators can streamline compliance reviews and accelerate approvals on new builds. The 1/2 in size with CLOSE threading shortens assembly time, minimizes stock variety, and simplifies raceway planning for engineers and installers. A light 0.052 lb weight per unit supports easier handling and lower logistics costs in large pull-and-fit deployments, making it ideal for high-volume maintenance cycles and standardized conduit runs.
