Eaton Crouse-Hinds ECLK436 S758 Explosionproof Coupling - Class I, Division 1
Part Number: ECLK436 S758
Quick Summary
The Eaton Crouse-Hinds ECLK436 S758 coupling provides a reliable, explosion‑proof connection for flexible conduit in hazardous locations. It supports a 1-1/4 in trade size with a 36 in flexible section, making it ideal for long, routed installations where accessibility is limited. This design targets Class I, Division 1, Class II, Division 1, and Class III environments, meeting NEC/CEC requirements for hazardous areas and offering UL-listed certification references. For procurement teams, the combination of forged brass material and a flexible PVC protective coating translates to durable performance and reduced maintenance. In practice, it enables faster field assembly while maintaining compliance, improving uptime and safety in oil, gas, chemical, and marine applications.

FAQs
To install the ECLK436 S758 safely, power must be off and wiring de-energized. Verify NEC/CEC compliance for your specific location, ensure correct mating of male/female ends, and secure conduit with appropriate sealing. Use the protective coating to resist moisture and chemicals, and follow Eaton’s installation guidelines to maintain UL certification status.
The ECLK436 S758 meets NEC/CEC standards for hazardous locations, with NEC Class I Division 1, Class II Division 1, and Class III ratings. UL certification references are available via the EC Explosionproof Couplings listings, including USA and Canada listings, and a dedicated Eaton specification sheet documents compliance and test data.
Yes. The ECLK436 S758 is designed as part of Eaton Crouse-Hinds EC explosionproof coupling family and uses standard male-female ends to mate with similar EC fittings. When selecting accessories, ensure matching thread size (1-1/4 in) and compatible materials to preserve the hazardous-location ratings and overall integrity of the conduit system.
The assembly provides a 41.75 in overall length, 2.94 in height and width, with a weight of 16.21 lb. The flexible section is 36 in long, and the trade size is 1-1/4 in. The 41.75 in length supports long conduit runs while the 36 in flex section enables easier routing in constrained spaces.
Ideal for oil and gas, chemical processing, and marine environments, where hazardous-area compliance is mandatory. It suits installation in exposed outdoor assets, offshore platforms, and plant facilities requiring reliable explosionproof coupling solutions with durable forged brass and PVC protection to withstand moisture, vibration, and chemical exposure.
