Compression connection delivers a secure, continuous electrical path with minimal installation steps. By eliminating threaded components, the threadless design reduces cross-threading failures while accelerating field assembly in tight panels and crowded conduits. It’s ideal for EMT conduit runs in control cabinets, motor rooms, and industrial spaces where reliability and ease of installation matter. Orange color enhances visual identification for circuit tracing and safety verification in high-visibility areas and temporary installations. This color-coding also helps installers coordinate with other Crouse-Hinds EMT fittings and reduces mistakes during maintenance. Steel construction provides robust mechanical strength and impact resistance in demanding industrial environments. The non-insulated design avoids extra insulation and simplifies thermal calculations, helping with enclosure planning in ordinary, dry locations. Trade size of 3 inches matches common EMT runs and aligns with standard conduit schedules, enabling straightforward compatibility with existing stock and catalogs. It integrates smoothly with Eaton Crouse-Hinds EMT fittings and supports fast field replacements using standard tools, while the 3.48 inch depth and 4.47 inch height help ensure predictable fitment in compact installations. Regulatory compliance is supported by NEC/CEC standards and UL listings for EMT connectors in the US and Canada, helping you meet code requirements without extra certification hunts. The Ordinary/Non-Hazardous area rating makes it suitable for typical plant floors and equipment enclosures, providing dependable performance across multiple shifts and environments. Installation resources and documentation are readily available to streamline procurement, design validation, and QC checks, including a 3D CAD drawing package and an official Eaton specification sheet. This support reduces engineering time and helps create accurate BOMs for project bidding and field deployment.

FAQs
To install, first ensure the conduit ends are clean and square. Insert the EMT into the connector until fully seated, then tighten the compression mechanism with standard hand tools or a torque-safe spindle as recommended by Eaton. Verify seating with a light pull test and check for uniform contact around the conduit perimeter to avoid gaps or misalignment.
The connector is straight, non-insulated, steel, and threadless, designed for EMT conduit up to a 3" trade size. It supports reliable electrical continuity, resistance to vibration, and compatibility with NEC/CEC requirements. In normal facility conditions, UL-listed for EMT fittings ensures compliance for both US and Canadian installations.
No, the product is rated for Ordinary/Non-Hazardous locations. For outdoor or hazardous environments, select fittings with appropriate IP ratings, weatherproofing, or explosion-proof certifications. Always verify the specific site requirements and consult Eaton catalogs for alternatives if needed.
This connector adheres to NEC/CEC standards and is UL-listed for EMT fittings in the US and Canada. It is intended for Ordinary/Non-Hazardous locations, which helps streamline code compliance and procurement within standard plant environments.
Eaton provides 3D CAD drawings, catalogs, and specification sheets for the 657ORANGE, enabling accurate modeling and BOM creation. Access to these resources reduces engineering time, supports fast procurement, and improves project certainty when budgeting and scheduling field execution.
