FAQs
ECLK18 is designed for Class I, Division 1 environments and uses forged brass construction to resist corrosion in harsh industrial settings. When installing, verify the 1/2 in trade size compatibility and ensure proper enclosure sealing per NEC/CEC guidelines. Use the 8 in flexible segment to route around obstacles, minimizing sharp bends. Always follow lockout/tagout procedures and consult the Eaton EC Explosionproof catalog page for guidance on mounting orientation and torque recommendations.
ECLK18 carries NEC/CEC standards for Hazardous/Classified Locations and a Class I, Division 1 rating, ensuring safe conduit connections in flammable or explosive atmospheres. The forged brass body, explosionproof design, and compliance documentation attest to its suitability for oil, gas, and chemical processing facilities, reducing the need for additional protective accessories while maintaining regulatory alignment.
Industries with stringent hazardous-location requirements benefit most, including oil and gas, chemical processing, refining, mining, and marine/oil platforms. The 1/2 in trade size and 8 in flexible length accommodate common conduit systems while the material and ratings support long service life in tough environments, contributing to safer installations and less maintenance downtime.
ECLK18 is specified under NEC/CEC standards for hazardous locations with Class I, Division 1 ratings. It also carries area-classification approvals for Hazardous/Classified Locations and Canadian certification references, which streamline cross-border compliance. Documentation and certification reports are available to validate the product’s compliance during audits and project submittals.
The forged-brass construction and explosionproof design yield longer service life in aggressive environments, lowering replacement frequency and maintenance costs. The 8 in flexible length and 1/2 in trade size reduce installation time and inventory complexity, speeding commissioning and enabling easier retrofits, which translates to lower total cost of ownership over the lifecycle of hazardous-location installations.
