Eaton Crouse-Hinds ECLK627 Coupling - Hazardous Locations
Part Number: ECLK627
Quick Summary
Eaton Crouse-Hinds ECLK627 coupling is a flexible conduit connector designed for explosion-protected installations in hazardous locations. Engineers often struggle with rigid fittings that slow field changes and can fail in harsh environments; this coupling addresses that by delivering durable, field-friendly routing. It carries NEC/CEC compliance and a Class I, Division 1 rating, with additional Class II/III consideration, enabling safer operations and regulatory alignment. The forged brass construction and 27 inch flexible length support reliable performance in demanding plants, while the 2 inch trade size ensures compatibility with standard conduit systems. By choosing this coupling, maintenance downtime is reduced and long-term lifecycle costs are minimized for hazardous-area installations.

Eaton Specification Sheet - ECLK627
Feature → Business Impact → Application: The 27-inch flexible length provides versatile routing and minimizes the number of fittings, reducing installation time and potential leakage points in complex conduit runs; this translates to faster commissioning and lower labor costs on hazardous-area projects. Application: Long-distance runs in confined spaces, where bend-free routing improves reliability and simplifies future modifications. Feature → Business Impact → Application: Forged brass construction delivers superior corrosion resistance and mechanical strength, extending service life in harsh environments and reducing replacement frequency. Application: Hazardous locations with chemical exposure or washdown requirements, including offshore or chemical processing facilities. Feature → Business Impact → Application: Male on one end and female on the other enables easy inline connections without adapters, cutting material waste and simplifying inventory management. Application: On-site installations where quick, secure coupling is needed during maintenance shut cycles. Feature → Business Impact → Application: 2" trade size ensures compatibility with standard conduit systems, minimizing compatibility issues and eliminating the need for specialty fittings. Application: Retrofit projects or new builds requiring reliable, readily available components. Feature → Business Impact → Application: NEC/CEC compliance and Class I, Division 1 rating provide regulatory assurance and safer operation, reducing risk of noncompliance penalties. Application: Plants in hazardous-classified locations needing UL-certified explosionproof couplings. Feature → Business Impact → Application: Lightweight at 1 lb with a 33.5 in product length option allows easier handling and alignment during installation. Application: Portable or overhead conduit runs in constrained spaces where weight savings matter.
