Eaton Crouse-Hinds NPL300300 Conduit Nipple - Rigid/IMC
Part Number: NPL300300
Quick Summary
NPL300300 conduit nipple from Eaton Crouse-Hinds provides a rugged rigid/IMC connection for steel conduit runs in industrial environments. A common pain point for installers is field-fit delays caused by corrosion-prone finishes and non-standard sizes. This nipple's galvanized steel and NEC/CEC alignment help reduce rework, while its 3x3 size supports predictable, fast installs. For procurement teams, the combination of weight (1.26 lb), standard conduit compatibility, and durable finish translates to lower cost of ownership. This makes it a reliable choice for control panels, enclosures, and field assemblies where durability, standardization, and regulatory compliance drive project timelines and total cost over time.

FAQs
The NPL300300 is designed for rigid/IMC conduit runs in industrial facilities. Its galvanized steel construction provides corrosion resistance, and the 3x3 size supports standard fittings in control panels, enclosures, and field assemblies. This makes it ideal for durable, code-compliant connections in non-hazardous environments where reliability matters most.
Yes. The NPL300300 lists NEC/CEC standards in its general specifications, and it is classified for Ordinary/Non-Hazardous Locations. This ensures regulatory alignment for installations in commercial and industrial settings, reducing compliance risk and the need for alternative fittings in standard conduit runs.
The galvanized finish provides enhanced corrosion resistance, extending service life in challenging environments and reducing maintenance cycles. It also helps preserve the appearance and integrity of conduit assemblies in exposed locations, contributing to lower replacement costs and fewer mid-project replacements.
Ensure compatibility with standard locknuts, washers, and reducers in the Eaton Crouse-Hinds line. The 3x3 size is designed for predictable mating with compatible rigid/IMC conduit components, facilitating faster assembly. Always verify the Ordinary/Non-Hazardous Location rating matches the installation environment.
Choosing the NPL300300 delivers reliable, code-compliant conduit connections with a durable galvanized finish, reducing rework and maintenance over the lifecycle. Its standardized size and weight support faster installs, lower labor costs, and streamlined procurement for mid-to-large scale electrical installations.
