Eaton ECLK26 Coupling - 3/4 in Trade Size, NEC Class I
Part Number: ECLK26
Quick Summary
The Eaton Crouse-Hinds ECLK26 coupling is a 6-inch flexible conduit connector designed for hazardous locations. This rugged unit addresses the real-world challenge of maintaining seal integrity and reliability on long runs in confined spaces, where abrupt movement or vibration can compromise safety. With NEC/CEC standards alignment and NEC hazardous ratings for Class I, Division 1, Class II, Division 1, and Class III environments, it delivers dependable performance where it matters most. The ECLK26 pairs with standard 3/4-inch trade-size conduits, forged brass construction, and a 10.13-inch overall length for versatile installations. For projects demanding compliance, ease of installation, and instrument-grade durability, this coupling reduces rework and downtime, delivering tangible ROI.

FAQs
Installation should follow standard conduit practices for hazardous locations. Ensure both ends are fully seated, tightening connectors to the manufacturer’s torque recommendations, and verify seals are intact before energizing. Use appropriate anti-spark tools and confirm compliance with NEC/CEC requirements for Class I, Division 1 installations. This approach minimizes leakage paths and maintains intrinsic safety margins while reducing rework and field maintenance.
The ECLK26 aligns with NEC/CEC standards and NEC hazardous ratings for Class I Division 1, Class II Division 1, and Class III environments. It is designed for Hazardous/Classified Locations and is referenced by certification reports and Eaton’s specification sheets. For Canadian projects, UL-based certification references are available, supporting compliance in multinational facilities and adding an extra layer of regulatory assurance.
Yes. The coupling is designed for 3/4 inch trade-size conduit and features male and female ends for straightforward installation with common EC explosionproof fittings. Its forged brass construction provides reliable mating with standard conduit hubs, improving retrofit compatibility and minimizing the need for specialized adapters in hazardous-location projects.
Plan for a 6-inch flexible length with an overall body length of 10.13 inches and a cross-section of 1.88 inches by 1.88 inches. The unit weighs approximately 2.45 pounds and uses a 3/4 inch trade size. The UPC for inventory and ordering is 782274259109, aiding accurate part identification during procurement and field service planning.
ECLK26 provides reliable hazardous-location performance with durable forged-brass construction, reducing corrosion-related failures and maintenance downtime. Its compliant NEC/CEC ratings streamline approvals, while the 6-inch flexible length and 3/4 inch trade size simplify installations, lowering labor time and total cost of ownership for critical facilities like refineries, chemical plants, and marine installations.
