Eaton Crouse-Hinds NPL50250 Conduit Nipple - 316SS
Part Number: NPL50250 316SS
Quick Summary
NPL50250 316SS conduit nipple provides a secure, corrosion-resistant connection for rigid/IMC conduit in industrial electrical enclosures. Engineers often struggle with leaks, misalignment, and rapid corrosion in harsh environments when hardware isn’t stainless or rated for the duty. This part aligns with NEC/CEC standards and UL Canadian certification, and it is suitable for ordinary/non-hazardous locations, enhancing life cycle cost and reliability. Its 1/2 in size and 2-1/2 in length, combined with 316 stainless steel, deliver durable, maintenance-friendly installations that reduce downtime and support compliant, long-term performance. Used in outdoor and washdown environments, it also complements stainless steel conduit fittings and locknut ecosystems to streamline field installations.

FAQs
Choose a 1/2 inch conduit diameter and 2-1/2 inch length to match standardRigid/IMC fittings. Use stainless steel locknuts and washers, ensure clean, undamaged conduit ends, and follow the catalog torque recommendations to avoid coupling loosening. The 316 stainless body should mate with compatible stainless hardware to maintain corrosion resistance in harsh environments.
316 stainless steel contains molybdenum, which significantly enhances resistance to chloride attack and chemical exposure common in coastal or industrial washdown scenarios. This material choice reduces surface pitting and rust, extending service life, lowering maintenance needs, and reducing the likelihood of conduit fittings failing under exposure to corrosive agents.
Yes. The part is designed for Ordinary/Non-Hazardous Locations and leverages 316 stainless steel to withstand outdoor and washdown conditions. Its robust corrosion resistance makes it suitable for outdoor panels, equipment racks, and other enclosures where environmental exposure is a concern, while NEC/CEC compliance ensures code-aligned performance.
The NPL50250 316SS conduit nipple adheres to NEC/CEC standards and carries UL Canadian certification, validating safety and performance for North American installations. It is specified for Ordinary/Non-Hazardous locations, aligning with typical industrial electrical codes and reducing compliance risk in regulated facilities.
The 316 stainless construction provides long-term corrosion resistance, minimizing replacement and maintenance costs. Its compatibility with standard conduit fittings and lightweight design speed installs, reducing labor time and downtime. For retrofit programs or high-volume deployments, these attributes translate into lower total cost of ownership and higher uptime.
