Eaton Crouse-Hinds NPL50350SA NPL conduit nipple - NEC/CEC
Part Number: NPL50350SA
Quick Summary
NPL50350SA conduit nipple provides reliable rigid/IMC aluminum connections for 1/2 in conduit runs in industrial electrical installations. This lightweight, corrosion-resistant fitting helps speed installs while maintaining mechanical strength. Installers often face weight, misalignment, and field corrosion that slow panel builds and drive rework. The NEC/CEC-compliant part is suitable for Ordinary/Non-Hazardous Locations, with UL certification references available for U.S. and Canadian use. By combining precise dimensions with a robust material, it supports quick, compliant terminations and reduced maintenance. In practice, customers benefit from easier field assembly, compatibility with standard locknuts and washers, and long-term lifecycle cost savings through lower weight and corrosion resistance.

NPL50350SA delivers a 1/2 in size with a 3.5 in length, forged in aluminum for rigid/IMC conduit connections. The aluminum construction reduces weight, improving handling in crowded enclosures and accelerating install timelines. When paired with standard locknuts and washers, it enables fast, code-compliant terminations with minimal field rework, a common source of project delays in machine builds and panel assemblies. The corrosion-resistant aluminum provides durability in ordinary/non-hazardous environments, extending service life and reducing maintenance cycles while supporting safer, more efficient installation practices. With rigid/IMC compatibility and the 1/2 x 3-1/2 in sizing, the nipple fits common enclosure openings, simplifying inventory management and accelerating procurement. This solution aligns with NEC/CEC requirements, helping OEMs and integrators maintain compliance while streamlining installation workflows. Finally, lightweight handling reduces worker fatigue on long runs, contributing to lower labor costs and faster project turnaround times.

FAQs
Installation begins with confirming a 1/2 in conduit, 3.5 in length, and aluminum construction for rigid/IMC connections. Use a compatible locknut and washer, thread the nipple into the enclosure or conduit hub, and tighten to the manufacturer’s torque spec. Ensure alignment is correct to prevent cross-threading and rework, then verify the connection for security and continuity.
The NPL50350SA is NEC/CEC compliant, designed for Ordinary/Non-Hazardous Locations. It aligns with common residential, commercial, and light-industrial conduit practices and is supported by UL certification references for U.S. and Canadian deployment. This ensures regulatory compliance, safer installations, and reduced risk of non-compliance penalties on projects.
Yes. The NPL50350SA is an aluminum, rigid/IMC conduit nipple sized 1/2 in x 3-1/2 in, engineered to integrate with standard aluminum conduit systems and common fittings such as locknuts and washers. Its rigid/IMC compatibility ensures a secure, durable joint, while using familiar accessories minimizes sourcing complexity and training needs for installers.
The NPL50350SA measures 1/2 in in size with a 3.5 in length, and features a width and height of about 0.84 in each. It weighs approximately 0.08 lb. These compact, lightweight dimensions simplify handling, reduce lifting strain during installation, and contribute to faster assembly in limited-space panels and cabinets.
