Eaton Crouse-Hinds ECLK24 coupling - Class I, Division 1
Part Number: ECLK24
Quick Summary
The Eaton Crouse-Hinds ECLK24 coupling is a 4 in flexible-ended conduit connector designed for hazardous locations. Installers often struggle with reliable sealing and safe mating in damp, explosive atmospheres, leading to downtime and ignition risks. This product carries NEC/CEC compliance and NEC hazardous ratings of Class I, Division 1, with additional Class II and Class III coverage where applicable, supported by UL certifications for hazardous locations. Its forged brass construction, precise 8.13 in length and 3/4 in trade size enable quick field assembly, reduced maintenance, and long-term reliability. For engineers and procurement teams, the combination of robust performance and global approvals translates to lower total cost of ownership and fewer schedule delays in demanding industrial environments.

FAQs
ECLK24 uses a 3/4 in trade size and a 4 in flexible length with male one end and female the other, designed to mate with standard EC explosion-proof fittings. This compatibility minimizes adapters and simplifies routing, reducing installation time in hazardous-area conduit runs and enabling reliable field connections.
ECLK24 carries NEC/CEC compliance and NEC hazardous ratings of Class I, Division 1, with additional Class II Division 1 and Class III coverage where applicable. It is UL-certified for hazardous locations, providing regulatory assurance for safety-critical installations in oil, gas, and chemical facilities and supporting cross-border projects.
Yes. The ECLK24 is designed for hazardous locations and uses forged brass construction with explosion-proof design principles. Its Class I, Division 1 rating, NEC/CEC compliance, and UL listings make it appropriate for offshore platforms, shipyards, and marine processing facilities requiring robust performance in corrosive and high-safety environments.
The 4 in flexible length reduces alignment constraints and allows easier routing around obstacles. Combined with male/female ends and a 3/4 in trade size, it minimizes extra fittings, lowers labor time, and enhances seal integrity in vibration-prone environments, delivering quicker, more reliable conduit connections in harsh settings.
Support materials include the Crouse-Hinds EC Explosionproof Couplings catalog page, UL certification reports, and Eaton’s ECLK24 specification sheet. These documents facilitate design validation, procurement decisions, and QA sign-off for projects in regulated industries such as oil & gas, chemical processing, and marine installations.
