Eaton Crouse-Hinds NPL400600 Conduit Nipple - Galvanized
Part Number: NPL400600
Quick Summary
NPL conduit nipple from Eaton Crouse-Hinds provides a rugged steel solution for rigid/IMC conduit runs used in industrial facilities. This part helps installers reduce field failures by providing a galvanised connection that resists corrosion in ordinary, non-hazardous locations. The design aligns with NEC and CEC requirements, with Canadian certification documentation available and industry-standard area classifications. By standardizing on the NPL400600, projects gain predictable fitment with compatible locknuts, washers, and reducers, while keeping weight manageable on-site. For procurement teams, this translates to consistent lead times, simpler stocking, and fewer last-minute substitutions across multiple projects. In short, it combines durable material with proven standards to support reliable, compliant wiring installations.
