Eaton Specification Sheet - ECLK127
Forged-brass construction provides excellent corrosion resistance and mechanical durability, reducing replacement costs and downtime in harsh environments. This translates into longer service life for hazardous area conduits and fewer field failures, enabling maintenance teams to plan replacements with confidence. The 1/2 in trade size standardizes kit compatibility across projects, minimizing the need for adapters and inventory variety while accelerating project timelines. The coupling offers a 27 inch flexible length and a total length of 30.75 inches, allowing easier routing through tight spaces and complex equipment layouts, which lowers installation time and labor costs. Male on one end and female on the other reduces mating errors and speeds up field assembly, even in restricted enclosures. NEC/CEC compliance and UL explosionproof certification provide regulatory assurance for global deployments, supporting safe, code-compliant installations across plants, refineries, and offshore facilities. The unit’s area classification of Hazardous/Classified Locations ensures suitability for Class I, Division 1 environments, enabling reliable operation in oil, gas, and chemical processing. Overall, the ECLK127 lowers maintenance frequency, improves installation consistency, and enhances safety in critical electrical infrastructure.

FAQs
The ECLK127 is a 1/2 in trade-size, forged-brass explosion-proof coupling with male and female ends. For compatibility, verify conduit type and size match (1/2 in), ensure the channel length accommodates a 27 inch flexible segment within a 30.75 inch overall length, and confirm NEC/CEC compliance for Class I, Division 1 locations. Use UL-listed mating components and follow manufacturer torque guidelines to maintain seal integrity and hazardous-location ratings.
ECLK127 carries NEC/CEC compliance and UL explosionproof certification, with Class I, Division 1 ratings documented for hazardous locations. The forged-brass construction resists corrosion and maintains mechanical integrity under vibration and temperature variations common in hazardous-area installations. The 1/2 in trade size and standardized ends support reliable, repeatable mating, reducing field failure rates and ensuring consistent performance across installations.
Yes. The ECLK127 is designed for hazardous/classified locations found in chemical plants and offshore environments. Its Class I, Division 1 rating and UL explosionproof certification make it suitable for oil, gas, and chemical processing applications. The 27 inch flexible length facilitates routing through tight spaces, while the overall 30.75 inch length accommodates long runs without compromising sealing or protection ratings.
Reference NEC/CEC compliance, Class I, Division 1 ratings, and UL explosionproof certification. The product is intended for hazardous locations and has area classification for Hazardous/Classified Locations. Use the UL certification pages and Eaton’s specification sheet for detailed verification, ensuring alignment with local electrical codes and project-specific explosionproof requirements across global sites.
The forged-brass construction offers durability and resistance to corrosion, reducing replacement and maintenance costs in harsh environments. Standard 1/2 in trade size minimizes spare-parts complexity, while the 27 inch flexible length and intuitive male/female ends shorten installation times. Compliance with NEC/CEC and UL certification lowers regulatory risk, supporting faster project approvals and lower long-term operational risk in hazardous-location power distribution.
