Eaton Specification Sheet - ECLK518
The ECLK518 delivers a key feature of an 18 inch flexible length with a forged brass body, enabling easier routing through confined spaces while maintaining mechanical integrity. This translates to a tangible business impact: faster field assembly and reduced downtime during maintenance cycles in hazardous environments such as chemical plants and offshore facilities. In practice, technicians appreciate the simple male end and female end compatibility, which minimizes misassembly risk and accelerates conduit integration into exposed electrical systems. The 1-1/2 inch trade size ensures compatibility with common conduit fittings, adapters, and strain-relief components, reducing inventory complexity and allowing standardization across projects. NEC/CEC compliance and UL listings for Class I, Division 1 locations provide regulatory confidence and documented safety margins, lowering audit exposure and insurance costs. The rugged forged brass construction withstands corrosive atmospheres and mechanical vibration typical of industrial installations, improving lifecycle value and asset uptime. Industry professionals also recognize that the ECLK518 integrates with EC explosionproof coupling families, delivering scalable solutions for growing plant footprints while preserving installation quality and performance.

FAQs
ECLK518 is engineered as an explosionproof coupling with NEC/CEC classifications and UL certification for Class I, Division 1 hazardous locations. The forged brass body, 18 inch flexible length, and 1-1/2 inch trade size ensure a secure, code-compliant connection between conduit segments, reducing ignition risk in flammable atmospheres and supporting compliant installation across petrochemical, refining, and marine facilities.
The 18 inch flexible length and dual-ended male/female connections simplify field routing, especially in tight spaces or irregular wiring paths. This design minimizes the need for additional adapters and reduces installation time, which translates to lower labor costs and less exposure to hazardous environments during assembly.
Verify the catalog number ECLK518, 18" flexible length, 1-1/2" trade size, forged brass material, and the dual gender ends. Also confirm NEC/CEC compliance and UL listings for Class I, Division 1. The standard dimensions (3.5 in height/width, 14.1 lb weight) support compatibility checks with existing conduit systems and mounting arrangements.
Yes. The ECLK518 is designed as part of Eaton Crouse-Hinds EC explosionproof coupling family and carries UL certifications for hazardous locations. This compatibility ensures consistent performance, simplified stocking of replacement parts, and predictable installation outcomes in high-risk environments.
The ECLK518 delivers a measurable ROI through faster installation, reduced risk of conduit leaks, and longer service life in corrosive environments. Its standardized 1-1/2 inch trade size and forged brass construction lower maintenance costs, while NEC/CEC and UL compliance help minimize regulatory downtime and inspection-related expenses over the system lifetime.
