Eaton 659BLUE EMT Compression Connector - Threadless
Part Number: 659BLUE
Quick Summary
659BLUE EMT compression connector is designed to join EMT conduits in industrial electrical installations. A common challenge is fast, error-free field assembly in crowded panels where misfit or insulation creates delay. This UL-listed, NEC/CEC-compliant connector is suitable for Ordinary/Non-Hazardous Locations and is color-coded blue for quick identification. By offering a blue, non-insulated steel connection with a threadless interface, it reduces installation time, minimizes tool requirements, and simplifies part management in large-scale projects. For engineers and procurement teams, it supports consistent quality, fewer SKU variations, and smoother commissioning of EMT conduit networks.

Eaton Specification Sheet - 659BLUE
Feature → Business Impact → Application: Straight, compression-type EMT connector in steel with a blue finish provides a robust mechanical grip and quick alignment, cutting field labor and rework when installing 4" trade-size conduits. This translates to measurable time savings on panel runs and improved project throughput in industrial facilities. Application: Ideal for control cabinets and industrial enclosures where color-coding and fast installation are priorities. Feature → Business Impact → Application: Threadless design eliminates cross-threading risk and simplifies hand-tightening in tight spaces, reducing tool wear and installation time in crowded installations. Application: Suitable for OEM assemblies and retrofit projects where space constraints are common. Feature → Business Impact → Application: Non-insulated insulation minimizes bulk at conduit joints and lowers heat buildup in dense wiring layouts, supporting thermal management in equipment racks. Application: Use in ordinary locations with NEC/CEC compliance requirements. Feature → Business Impact → Application: Blue color aids visual identification during conduit routing, improving wiring traceability and reducing miswiring in complex conduit networks. Application: Applies to large-scale installations with color-coded EMT runs. Feature → Business Impact → Application: UL listing for EMT fittings plus NEC/CEC compliance provides regulatory assurance, reducing QA overhead and accelerating approvals. Application: Preferred for safety-critical builds and facilities requiring certification traceability.

FAQs
The 659BLUE is a straight, non-insulated, steel EMT compression connector with a threadless interface, designed for 4" trade size conduits. It requires standard EMT field install tools and clamps into EMT runs without threading, reducing installation time. Ensure proper seating to achieve the compression seal and confirm NEC/CEC compliance for ordinary locations. Color coding aids quick identification in crowded panels, supporting faster commissioning and fewer wiring errors.
The 659BLUE is NEC/CEC compliant and UL listed for EMT fittings, with certification documents accessible through the provided UL pages. Its area classification is Ordinary/Non-Hazardous Locations, making it suitable for typical industrial and commercial environments. This combination of standards ensures regulatory alignment, safer installations, and streamlined inspections for control cabinets and distribution panels.
Yes. The 659BLUE is part of the Crouse-Hinds EMT family and is designed to mate with compatible EMT conduits and fittings from the same series. Its straight, compression, threadless design supports reliable, uniform connections across multiple joints, reducing mismatch risk and simplifying stock management for panel builders and system integrators.
The 659BLUE combines durable steel construction, a blue color for quick routing, and a threadless compression mechanism that lowers installation time and reduces labor costs. Its non-insulated design minimizes bulk at joints, improving conduit routing in dense environments. UL/NEC/CEC compliance reduces QA and approval cycles, delivering faster project readiness.
Key specs include Catalog Number 659BLUE, UPC 662277090575, Product Length 3.84 in, Height 5.59 in, Width 5.59 in, and Weight 3.6 lb. It is a blue, non-insulated, steel straight connector for EMT conduit with a 4" trade size and threadless connection. Also verify color coding for identification and ensure ordinary location suitability per NEC/CEC.
