FAQs
NPL125400 is a 1-1/4 in diameter by 4 in long conduit nipple made from 316 stainless steel for rigid/IMC conduit. It is designed for ordinary/non-hazardous locations and should be paired with compatible fittings and nuts. For best results, consult the Eaton specification sheet and ensure mating components match the 1-1/4 in size and IMS threading where applicable. Proper tightening and alignment reduce leaks and damage to the conduit system.
Yes. The product lists NEC/CEC standards as part of its certifications and is rated for Ordinary/Non-Hazardous Locations. This ensures code-compliant installations across North American facilities and supports regulatory auditing. Always verify local code requirements and project specifications, but this nipple is designed to meet common electrical installation standards for industrial environments.
316 stainless steel provides excellent corrosion resistance, particularly in washdown and chemical exposure scenarios. The material choice translates to longer service life, lower maintenance costs, and reduced replacement cycles. This is especially valuable in facilities where stainless steel fittings are preferred for durability and hygiene, such as food processing or chemical plants.
Best suited for general industrial and manufacturing settings requiring rigid/IMC conduits in ordinary locations. Its corrosion resistance makes it suitable for washdown zones, outdoor installations, and chemical environments where stainless steel fittings help maintain integrity and performance. It is a practical choice for OEMs and maintenance teams seeking reliable, long-lasting conduit terminations.
Eaton provides a specification sheet and related catalogs for the NPL125400 316SS. The official Eaton page hosts the spec sheet, and additional catalog pages cover locknuts, nipples, washers, reducers, and plugs for rigid-IMC systems. Access these documents to confirm dimensions, materials, and installation guidance before procurement.
