FAQs
To install the ECLK112, ensure the conduit ends are clean and compatible with a 1/2 in trade size. Align male and female ends, hand-tighten to seat, then perform a final torque check per the Eaton specification sheet. Use appropriate sealing materials for the environment and verify the assembly remains within the hazardous-location rating after installation.
The 12-inch flexible length provides versatile routing where rigid fittings would be impractical, reducing the number of additional couplings required. The 1/2-inch trade size aligns with typical conduit hardware, ensuring a secure fit and reliable seal under vibration and temperature changes common in hazardous locations.
Yes. The ECLK112 is designed to meet NEC/CEC hazardous-location standards and is specified for Class I, Division 1. Its classification supports broader use across Class II and III locations as documented by the NEC/CEC standards, with UL certifications validating safe operation in these environments.
The ECLK112 carries NEC/CEC compliance for hazardous locations and UL certifications for use in such environments. These certifications confirm suitability for Class I Division 1 locations and related hazardous-area applications, aiding in code compliance during inspection and commissioning.
The forged brass construction and robust explosionproof design resist corrosion and wear, lowering maintenance frequency. Its simple male-female connection and 12-inch flexible length reduce installation time and spare-part requirements, delivering a quicker return on investment through decreased downtime and safer, compliant conduit assemblies.
