Eaton Specification Sheet - ECGJH621 S516
The 21-inch flexible length provides routing adaptability that reduces field labor and fumbling during installation, improving turnaround time and minimizing mechanical strain on conduits. This translates to measurable efficiency gains on project floors and service calls, with less rework and faster uptime in hazardous areas. The stainless steel construction offers exceptional corrosion resistance, extending service life in offshore, chemical, and marine environments while lowering replacement costs. Male connections on both ends simplify integration with existing conduit networks, reducing connection time and ensuring a secure seal in confined spaces. IP66 ingress protection guards against dust ingress and water exposure, supporting reliable operation in dirty or wet industrial settings and compliance with strict safety standards. Certifications including NEC/CEC IECEx/ATEX further simplify procurement and installation by confirming suitability for Class I, II, and III locations, reducing regulatory risk. Compatibility with Crouse-Hinds EC explosion-proof coupling families enhances interchangeability and stock planning, delivering a smoother maintenance workflow and vendor consolidation for engineering teams who need proven, field-ready fittings.

It is compatible with IECEx/ATEX, NEC/CEC standards, and IP66-rated environmental protection, making it suitable for Class I, II, and III installations in industrial, chemical, and offshore settings.
The coupling complies with NEC/CEC and IECEx/ATEX standards for explosion-protected equipment, aligned with NEC Class I, II, III Division 1 ratings. It is designed for Hazardous/Classified Locations and carries an IP66 ingress protection rating, ensuring robust safety performance and simplifying regulatory acceptance for global projects.
Yes. Constructed from stainless steel with IP66 protection, the ECGJH621 S516 is engineered for harsh offshore and marine environments where exposure to salt spray, humidity, and dust is common. Its hazardous-location ratings, flexible length, and reliable male-male end connections support durable service in demanding marine electrical installations.
The 21 inch flexible length accommodates misalignment and routing challenges, reducing the need for custom fabrication or spacers. This flexibility speeds up assembly, minimizes labor costs, and lowers the risk of stress on conduit runs, which benefits project timelines and long-term reliability in constrained hazardous spaces.
The corrosion-resistant stainless steel and IP66 protection provide extended service life, reducing replacement and maintenance needs in tough environments. Certification alignment with NEC/CEC IECEx/ATEX simplifies audits and procurement, while the durable design lowers downtime and supports a faster return on investment for facilities operating in hazardous areas.
