Eaton Crouse-Hinds ECLK612 Coupling - Hazardous Locations
Part Number: ECLK612
Quick Summary
Eaton Crouse-Hinds ECLK612 is a 12-inch flexible conduit coupling used to join male and female ends in Hazardous Locations. Field installs often struggle with vibration, moisture ingress, and compliance gaps in explosive atmospheres. This coupling meets NEC/CEC standards and hazardous-area ratings, supporting Class I, Division 1, Class II, Division 1, and Class III environments. Its forged brass construction delivers durability in rugged sites, while the 12-inch length and 2-inch trade size streamline installations, reduce spares, and improve uptime. Designed for seamless compatibility with EC explosionproof fittings, it helps maintain regulatory compliance while minimizing field rework and maintenance costs. Free-spanning accessibility simplifies inspection.

Eaton Specification Sheet - ECLK612
12-inch flexible length enables routing around equipment and through tight enclosures, reducing the number of elbows and adapters required in hazardous-area runs. This directly lowers installation time and minimizes potential leak paths, helping maintain system integrity in Class I Division 1 environments. Ideal for offshore platforms, chemical processing facilities, and other demanding hazardous locations where space is at a premium. Male on one end and female on the other provide field versatility and plug-and-play compatibility with standard EC explosionproof fittings. This reduces the number of spare parts engineers must carry and accelerates commissioning, especially in retrofit or expansion projects. Forged brass construction delivers robust durability and corrosion resistance in harsh environments, including salt spray and humidity common to marine facilities. The long service life translates into lower maintenance costs and fewer replacements over the system's life. NEC/CEC compliance and explicit hazardous-location ratings (Class I, Division 1; Class II, Division 1; Class III) give confidence during design reviews and inspections. This compatibility with Canadian and US standards helps streamline procurement and avoid rework. 2-inch trade size compatibility with standard EC explosionproof fittings simplifies integration into existing conduit networks, and the 18.5-inch overall length fits typical spacing between terminations. Access to Eaton's specification sheet and catalog page enables rapid validation during procurement and safe installation.

FAQs
The ECLK612 is designed for EC explosionproof conduit systems and features a male end on one side and a female end on the other, with a 2" trade size. It enables direct, secure connections in hazardous locations and is designed to work with standard EC fittings, reducing the need for adapters and simplifying field retrofits.
The ECLK612 supports NEC/CEC compliance for hazardous locations with ratings including Class I, Division 1; Class II, Division 1; and Class III, aligning with NEC hazardous-area requirements and facilitating safe operation in oil, gas, and chemical processing environments.
Yes. The ECLK612 uses forged brass and is designed for harsh environments common to marine facilities, offering durability, corrosion resistance, and reliable performance in splash zones and salt spray conditions typical of offshore platforms.
Ensure the 12-inch flexible length, 2-inch trade size, and the male/female ends align with your EC explosionproof fittings. Refer to the Eaton ECLK612 specification sheet for torque, sealing, and mounting guidance to maintain NEC/CEC compliance and electrical integrity in hazardous locations.
The forged brass construction provides extended service life with low corrosion risk, reducing maintenance cycles and part replacements. Its 12-inch length and modular connection design shorten installation time and commissioning, delivering a favorable total cost of ownership in hazardous-area conduit networks.
