Eaton Crouse-Hinds NPL50300 Conduit Nipple - Galvanized
Part Number: NPL50300
Quick Summary
NPL50300 conduit nipple from Eaton Crouse-Hinds provides durable, galvanized steel connections for rigid/IMC conduit in electrical installations. Field technicians often struggle with corrosion protection and reliable fittings in damp or outdoor environments, causing maintenance delays. This NPL50300 meets NEC/CEC requirements and UL certification for North America, while its galvanized finish resists corrosion in ordinary locations. The combination of robust steel construction and regulatory compliance delivers faster panel builds, lower rework, and longer service life for industrial wiring projects. In addition, using this nipple supports efficient procurement with standardized catalog references and cross-functional compatibility.
