Eaton Crouse-Hinds ECLK318 Coupling - Hazardous Locations
Part Number: ECLK318
Quick Summary
The Eaton Crouse-Hinds ECLK318 coupling provides a flexible 18-inch conduit connection for hazardous locations. Field installs often struggle with slow assembly, risky seals, and incompatible fittings in harsh environments. This product delivers NEC/CEC compliance and hazardous-location ratings—Class I, Division 1; Class II, Division 1; and Class III—supporting regulatory acceptance. Built with forged brass and a 1" trade size, it resists corrosion and fits standard conduit systems for reliable, long-term operation. In practice, this translates to reduced installation time, fewer callbacks, and improved safety margins across your hazardous-area electrical infrastructure. Designed for OEMs, integrators, and maintenance teams, it supports scalable conduit runs without compromising safety or compliance.

Eaton Specification Sheet - ECLK318
Feature: 18-inch flexible length enables versatile routing in confined electrical enclosures. Business Impact: reduces the number of elbows and fittings, shortening installation time and minimizing panel space usage in hazardous-area installations. Application: industrial automation cabinets and instrument enclosures where space is constrained. Feature: Male one end, female connection on the opposite end. Business Impact: simplifies mating and alignment, lowers field labor costs, and reduces the risk of cross-threading during assembly. Application: quick field splices in explosion-proof conduit runs. Feature: Forged brass construction. Business Impact: provides robust mechanical strength and corrosion resistance in harsh environments, extending service life and lowering maintenance cycles. Application: chemical processing, oil & gas, and mining facilities with aggressive media. Feature: 1" trade size. Business Impact: standardizes compatibility with common conduit systems, streamlines procurement, and reduces BOM complexity. Application: construction-ready and retrofit projects requiring reliable stock-keeping. Feature: NEC/CEC compliance and hazardous-location ratings. Business Impact: ensures regulatory acceptance, simplifies inspection processes, and mitigates compliance risk in Class I, Division 1, II, 1, and III environments. Application: any certified hazardous-area conduit installation. Feature: Catalog and datasheet accessibility (UL Canada certs and Eaton spec sheet). Business Impact: supports design validation, accelerates supplier qualification, and improves project documentation. Application: engineering design reviews and procurement workflows in safety-critical facilities.

FAQs
The ECLK318 installs like a standard explosion-proof conduit coupling with a male end and a female end. Ensure proper termination, tighten connections to recommended torque, and verify a secure seal per NEC/CEC guidelines. Use compatible conduit, gaskets, and seals designed for hazardous areas to maintain integrity and safety.
Key specs include 18-inch flexible length, 1-inch trade size, forged brass construction, and a male/female end configuration. The unit supports Class I, Division 1, Class II, Division 1, and Class III hazardous locations, aligning with NEC/CEC standards and Canadian certifications for regulatory compliance.
Yes. The ECLK318 is designed for 1" trade-size installations and features a standard male-female coupling interface, enabling straightforward integration with common conduit runs, accessories, and conduit bodies used in industrial automation and hazardous-area projects.
The ECLK318 meets NEC/CEC requirements for hazardous locations and carries Class I, Division 1 (as well as Class II and Class III) ratings. Certification documents include Canadian certification references and the Eaton specification sheet, supporting compliance during audits and inspections.
The 18-inch flexible length and forged brass construction enable rapid installs with durable sealing in harsh environments, reducing downtime and maintenance costs. Its compatibility with standard 1" conduit reduces stocking complexity, while NEC/CEC compliance minimizes regulatory risk during upgrades or expansion of hazardous-area electrical systems.
