Eaton Crouse-Hinds 1031NI Throat Bushing - Rigid/IMC
Part Number: 1031NI
Quick Summary
1031NI throat bushing is a compact conduit fitting that secures rigid/IMC transitions in electrical panels, enclosures, and industrial installations. Engineers often contend with vibration, misalignment, and sealing gaps that degrade performance, drive maintenance costs, and extend project schedules. This Eaton Crouse-Hinds model aligns with NEC/CEC standards and is classified for Ordinary/Non-Hazardous Locations, with Canadian certification options supported by supplier documentation. Its malleable iron construction, non-insulated design, and 1/2 inch threaded connection enable fast, reliable installs that stay seated under vibration while meeting code requirements. By delivering predictable dimensions and clear specifications, it reduces field rework, supports compliant installations, and improves overall system uptime for harsh industrial environments.

FAQs
The 1031NI supports rigid/IMC conduit with a 1/2 inch trade size. It features a threaded connection and non-insulated design made from malleable iron, suitable for standard 1/2 inch IMC terminations in non-hazardous environments. This provides a straightforward, reliable fit for most panel and enclosure installations.
Key specs include a 1/2 inch trade size, rigid/IMC conduit compatibility, threaded connection, non-insulated insulation, malleable iron material, dimensions of 1.06 in length and width, 0.63 in height, and a weight of 0.07 lb. UPC is 662277003414. Catalog references and datasheets confirm these parameters for engineered compliance.
The 1031NI is classified for Ordinary/Non-Hazardous Locations and adheres to NEC/CEC standards. While suitable for non-hazardous environments, customers should verify project-specific location classifications. Canadian certification references are available, and UL listings in supplier documentation support cross-border applications when applicable.
Its threaded 1/2 inch connection and non-insulated design simplify terminations, reducing assembly steps and torque checks. The compact malleable iron body resists vibration and maintains seating under operation, cutting field rework and downtime. This translates to faster panel builds, lower labor costs, and improved system uptime in production cells.
Ensure the conduit is clean and threads are undamaged before installation to prevent cross-threading. Use proper thread sealant or torque per manufacturer guidelines to achieve a reliable seal. Confirm the 1/2 inch trade size and IMC compatibility, and verify that the installation location adheres to NEC/CEC requirements for ordinary locations.
