Eaton Specification Sheet - ECLK424
The 24-inch flexible length provides route flexibility and minimizes field splicing, reducing labor time and potential leakage in hazardous areas. This translates to quicker installations and lower maintenance costs on new builds or upgrades in chemical processing facilities. The 1-1/4 inch trade size standardizes interfaces across conduit systems, simplifying procurement and reducing the risk of misfits during installation in plant environments. Forged brass construction delivers durable performance in corrosive or harsh settings, extending service life and lowering replacement cycles for hazardous area equipment. Male on one end and female on the other enables straightforward assembly in tight spaces, speeding service calls and reducing downtime during maintenance windows. Compliance with NEC/CEC standards and UL explosionproof certification provides a clear path for regulatory approval, reducing engineering review time and enabling safer project handoffs. The overall length of nearly 30 inches supports routing across equipment clusters while maintaining robust mechanical integrity, a benefit when retrofitting existing installations in hazardous classified locations. This coupling integrates with EC explosionproof systems, aligning with industry best practices for hazardous area conduit fittings and helping contractors meet project timelines and budget targets.

FAQs
Begin by verifying conduit compatibility and confirming Class I, Division 1 suitability. Connect the male end to one section of conduit and the female end to the opposing run, ensuring all seals are intact and tightened per Eaton's guidelines. Use proper torque and threading procedures, then test the assembly for sterility and leakage before energizing equipment.
The ECLK424 carries NEC/CEC compliance with Area classification for Hazardous/Classified Locations and UL explosionproof certifications, including Class I, Division 1 ratings. These credentials matter because they simplify regulatory approvals, reduce risk during audits, and ensure safe operation in hazardous environments such as chemical plants and oil refineries.
Yes, it is designed for hazardous area and marine equipment use, leveraging forged brass construction and explosionproof ratings appropriate for harsh, humid environments. Always verify local marine and regulatory requirements, but this coupling supports rugged installations with approved conduit connections in challenging offshore settings.
Key specs include a 24-inch flexible length, 29.75-inch overall product length, a 1-1/4 inch trade size, forged brass material, and a male/female end configuration. The UPC is 782274262901, and the product is rated for hazardous locations under NEC/CEC with Class I, Division 1 approval.
The ECLK424 reduces installation time through its flexible routing and quick-connect ends, lowers splicing needs, and minimizes downtime during maintenance. Its certified compliance lowers the risk of nonconformance, helping projects stay on schedule and reducing total cost of ownership over the equipment’s life cycle.
