Eaton Crouse-Hinds ECLK127 S758 Explosionproof Coupling
Part Number: ECLK127 S758
Quick Summary
Eaton Crouse-Hinds ECLK127 S758 explosionproof coupling provides flexible, safe conduit connections for hazardous locations. Installing fixed fittings in Class I Division 1 environments often leads to scheduling delays and costly rework, especially in tight spaces. This product carries UL explosionproof certification and NEC/CEC compliance, with hazard-location ratings for Class I Division 1, Class II Division 1, and Class III. Designed for offshore platforms, refineries, and chemical processing plants, it offers a robust alternative to rigid fittings. By combining a forged brass body with a PVC protective coating, it delivers long-term durability and easier maintenance, while the 1/2 inch trade size and 27 inch flexible length support faster, safer installations and scalable plant-wide connectivity.

FAQs
The ECLK127 S758 uses a 1/2 inch trade size with a male connection on one end and a female connection on the other, aligning with standard EC series conduit fittings. Its 27 inch flexible length allows routing around obstacles in hazardous locations, while NEC/CEC compliance ensures regulatory compatibility. When pairing with EC explosionproof fittings, verify thread standards and gasket seals to maintain the explosionproof integrity during installation.
This coupling is UL-certified for explosionproof use and meets NEC/CEC standards for hazardous locations. It carries area classifications suitable for Class I, Division 1, Class II, Division 1, and Class III environments. Canada certifications are referenced via UL listings, ensuring compliance for North American oil, gas, and chemical processing facilities. Always cross-check with the latest UL certificate pages during procurement to confirm scope and update status.
The 27 inch flexible length reduces the need for multiple fittings and field fabrication, lowering installation time and potential leak paths. Forged brass provides structural integrity and corrosion resistance, while the PVC protective coating guards against solvents and moisture. The combination supports faster commissioning, easier maintenance, and longer service life in remote or offshore installations where downtime is costly.
Yes. The ECLK127 S758 is designed for hazardous areas and marine equipment use, including Class I Division 1 locations. Its explosionproof construction, corrosion-resistant brass with PVC coating, and EC series compatibility make it well-suited for offshore platforms, refineries, and chemical processing facilities where exposure to salt spray and aggressive chemicals is common. Always verify environmental approvals and vessel-level requirements before deployment.
The forged brass body and PVC coating deliver durable performance with excellent corrosion resistance, reducing replacement frequency in harsh environments. The 1/2 inch trade size and flexible 27 inch length enable simpler maintenance routing and easier retrofits, lowering total cost of ownership over time. Regular inspection of seals and gaskets, along with adherence to NEC/CEC maintenance guidelines, helps sustain peak performance and safety.
