Eaton Crouse-Hinds ECLK618 Coupling - Hazardous Locations
Part Number: ECLK618
Quick Summary
The ECLK618 coupling by Eaton Crouse-Hinds is a rugged 18-inch flexible coupling for hazardous-location conduit connections. Engineers often struggle to maintain seal integrity and install fittings quickly in explosive atmospheres, especially under demanding temperature cycles, tight spaces, and retrofit projects. This unit carries NEC/CEC certification for Hazardous/Classified Locations and is rated Class I, Division 1; Class II, Division 1; and Class III environments. Built with forged brass and a 2-inch trade size, it delivers durable performance and predictable field installability, reducing rework and maintenance costs for compliant electrical installations in harsh settings.

Feature: 18-inch flexible ECLK618 coupling with 2-inch trade size and both male and female ends, constructed from forged brass. Business Impact: Provides a versatile, high-strength connection that simplifies routing across equipment enclosures and reduces the need for multiple adapters, cutting parts counts and field labor. Application: Ideal for long conduit runs where space is constrained and a robust, leak-resistant seal is required in hazardous locations. Feature: Hazardous-location rating aligned with NEC/CEC standards and Class I, Division 1; Class II, Division 1; Class III. Business Impact: ensures regulatory compliance and operational safety, reducing audit findings and potential downtime. Application: suitable for oil & gas, chemical processing, and marine installations where explosion-proof robustness is mandatory. Documentation includes Canadian certification references for cross-border projects. Feature: Forged brass body with durable construction; weight and dimensions provide strong mechanical integrity. Business Impact: reduces maintenance costs due to corrosion resistance and less frequent part replacement. Application: performs reliably in harsh environments, including offshore platforms and chemical plants. Feature: Clear documentation and compatibility resources, including catalog pages and specification sheets. Business Impact: accelerates procurement and ensures correct part selection, minimizing procurement errors. Application: procurement teams reference official Eaton materials (ECLK618) during specification and job pack development. The availability of CAD-friendly drawings and spec pages helps procurement integrate with ERP and BOM workflows. Feature: Precise dimensions—24.5 in length, 4.25 in width/height, 22.2 lb weight; 18 in flexible length, 2 in trade size; two ends gendered for easy installations. Business Impact: provides a predictable install footprint, reduces field modifications and scheduling delays. Application: helps hazardous-location installations and retrofits by ensuring proper fit and seal integrity. Feature: Proven compatibility with standard conduit runs and Eaton EC explosion-proof fittings line, reducing engineering changes during upgrades. Business Impact: minimizes rework and supports fast commissioning, especially in multi-vendor sites. Application: ideal for new builds and retrofits in chemical plants, refineries, and offshore facilities where schedule and safety are paramount.

FAQs
ECLK618 uses a 2 inch trade size with male one end and female the other, designed for standard conduit systems. Its forged brass construction supports reliable connections in Class I, Division 1 hazardous locations, while maintaining compatibility with common conduit fittings and installation practices used in oil, gas, and chemical facilities.
ECLK618 is certified for Hazardous/Classified Locations under NEC/CEC standards and rated Class I Division 1, Class II Division 1, and Class III. Canadian certification references are available in the provided documentation, supporting cross-border project compliance and traceability during audits and inspections.
Yes. The ECLK618 is designed for hazardous-location environments common in offshore platforms and marine facilities. Its forged-brass construction and explosion-proof ratings help meet stringent regulatory requirements, while its 18-inch flexible length and 2-inch trade size enable robust, field-installable connections in challenging marine spaces.
Maintenance considerations center on ensuring the gasket/threads remain clean and free of debris, verifying torque as per installation guidelines, and inspecting for corrosion resistance of the forged-brass body. The unit’s durable construction reduces the frequency of part replacement, supporting lower lifecycle costs in demanding industrial settings.
Official documentation includes the Crouse-Hinds EC catalog page, the ECLK618 specification sheet, and Canadian certification references. CAD-friendly drawings and spec pages are available to accelerate procurement, BOM integration, and job-pack preparation, reducing mis-specification and sourcing delays on complex projects.
