FAQs
Installation guidance for the ECLK121 S758 emphasizes adherence to NEC/CEC requirements and equipment clearance per local codes. Verify the 1/2 in trade size and 24.75 in length fit your conduit runs, ensure proper gasket and mounting hardware are used, and confirm the male/female ends meet the mating connectors. In hazardous locations, always de-energize circuits and follow lockout/tagout procedures. The beveled brass body and flexible PVC coating aid ease of handling while maintaining seal integrity in Class I, II, and III environments.
Yes. The ECLK121 S758 is designed for compatibility with standard EC explosionproof coupling families, sharing the same trade size and connection geometry. When integrating with other EC components, maintain consistent conductor sizing, ensure matching thread forms, and verify compatibility with your conduit material. This compatibility reduces the need for adapters, minimizes installation time, and supports scalable deployments in large hazardous-location projects.
The ECLK121 S758 carries NEC/CEC standards compliance and hazardous-location ratings, including Class I, Division 1; Class II, Division 1; and Class III. This ensures suitability for hazardous/classified locations as defined by NEC. UL certification pages and EC catalog documentation validate performance and safety, supporting audits and regulatory adherence in chemical plants, oil and gas facilities, and offshore installations.
Key specifications include a 24.75 in overall length, 1/2 in trade size, forged brass construction, flexible PVC protective coating, and a 21 in flexible segment with male one end and female on the opposite end. The UPC is 782274587400, and the product name is Eaton Crouse-Hinds series ECLK coupling. These specs inform routing, compatibility with existing EC explosionproof fittings, and compliance with hazardous-location requirements across NEC/CEC frameworks.
Industries such as oil and gas, chemical processing, marine, and offshore facilities benefit most due to the combination of explosionproof ratings and durable materials. ROI stems from reduced installation time thanks to the 21 in flexible segment, fewer fittings, and fewer maintenance interventions thanks to forged brass with protective coating. Compliance with NEC/CEC and UL certifications also lowers risk-related costs and simplifies regulatory audits.
