Eaton Specification Sheet - ECLK212
The 12-inch flexible length with a male one-end and female opposite-end connection enables easier routing around obstacles, reducing field assembly time and minimizing the risk of misalignment in tight installations. This directly improves project timelines and lowers labor costs in hazardous-area projects where downtime is especially costly. The forged brass construction provides excellent corrosion resistance and durability in challenging environments such as chemical plants, offshore platforms, and industrial facilities, extending service life and reducing replacement cycles. A 3/4-inch trade size ensures compatibility with standard conduit fittings, decreasing parts diversity and accelerating procurement while simplifying installation for installers and OEMs. NEC/CEC compliance with Hazardous/Classified Locations and Class I, Division 1 ratings—bolstered by UL certification—shrinks regulatory risk and supports safer, compliant deployments across facility upgrades. The 16.13-inch product length and compact 1.88-by-1.88-inch footprint, combined with a 3.05 lb weight, enable reliable mounting in conduit runs without excessive bulk, aiding planning and field reliability. This makes the ECLK212 a practical choice for both new installations and retrofit projects in automation and electrical infrastructure.

FAQs
When installing ECLK212, plan for the 12-inch flexible length to navigate around obstacles and align with the 3/4-inch trade size fittings. Ensure the male and female ends are properly engaged and that the conduit run complies with NEC/CEC Hazardous Location requirements. Use UL-certified practices and verify Class I, Division 1 ratings are applicable to the installation site.
Yes. ECLK212 is part of Eaton Crouse-Hinds’ EC explosionproof couplings family. Refer to the EC catalog page for matching dimensions and compatibility to ensure seamless integration with existing conduit systems and to validate installation procedures for hazardous locations.
ECLK212 carries NEC/CEC standards for Hazardous/Classified Locations, with Class I, Division 1 ratings and UL certification for hazardous locations. This combination supports compliance in regulated environments and provides confidence in safe, compliant installations for your hazardous-area electrical infrastructure.
The 12-inch flexible length reduces rigid bending requirements, allowing faster routing around obstacles and easier alignment with other fittings. This translates to shorter installation times, fewer field adjustments, and reduced labor costs, while preserving the integrity of hazardous-location connections and maintaining compliance in challenging environments.
By combining a robust forged-brass body with UL-listed protection and NEC/CEC compliance, the ECLK212 lowers regulatory risk and prolongs service life in harsh environments. The flexible design reduces installation time and maintenance, contributing to lower total cost of ownership and improved uptime for automation and electrical infrastructure projects.
