Eaton Crouse-Hinds ECLK430 Explosionproof Coupling - Hazardous
Part Number: ECLK430
Quick Summary
ECLK430 is a flexible explosionproof coupling for hazardous-location conduit installations in chemical and offshore facilities. Rigid connections can crack or leak under vibration, leading to downtime, maintenance, and safety risks. Designed to NEC/CEC requirements for Hazardous/Classified Locations and Class I, Division 1 ratings, it helps keep critical systems compliant. Its 30-inch flexible length and forged brass body provide quick, code-compliant installations with reliable sealing. In practice, this means reduced commissioning time, safer cross-location transitions, and lower total cost of ownership for hazardous-area projects. The unit supports versatile field installation, enabling seamless upgrades and consistent performance across demanding environments.

FAQs
The ECLK430 is designed for hazardous-location conduit connections, supporting NEC/CEC compliance and Class I, Division 1 ratings. It excels in chemical processing plants, offshore platforms, and other environments where explosionproof performance and flexible routing are required. Its 30" length and male/female ends simplify long runs and complex installations while maintaining seal integrity.
The ECLK430 adheres to NEC/CEC standards for Hazardous/Classified Locations and is rated for Class I, Division 1. This certification ensures safe operation in potentially explosive atmospheres, providing reliable coupling performance under vibration and temperature variations common in industrial and marine environments.
Yes. With a 1-1/4" trade size and forged brass construction, the ECLK430 integrates with standard conduit fittings and flex expectancies. The male/female dual-end design offers installation flexibility, reducing the need for adapters and minimizing potential leak points on long conduit runs.
Maintenance is straightforward: inspect for seal integrity and corrosion resistance, particularly in corrosive or marine environments. The forged brass body provides robust corrosion resistance, and the coupling’s design supports easy inspection and replacement of fittings, contributing to lower lifecycle maintenance costs.
The ECLK430 can reduce commissioning time and labor costs thanks to its long 30" flexible length and dual-end design, while meeting stringent NEC/CEC compliance. By lowering downtime risk and accelerating installation, it offers tangible value through improved reliability, safer operations, and lower total cost of ownership in hazardous-location conduit networks.
