FAQs
To install the ECLK624, follow NEC/CEC guidelines for hazardous locations, align the male and female ends, and secure with appropriate fittings and seals specified for Class I Division 1 environments. Use the product’s 24" flexible length to minimize elbows and ensure a tight, code-compliant connection. Verify the 2" trade size matches your conduit system and inspect for proper sealing after installation.
The ECLK624 carries NEC/CEC standards with NEC hazardous ratings for Class I Division 1, Class II Division 1, and Class III. It is intended for Hazardous/Classified Locations, aligning with industry requirements for explosion-protected conduit couplings. This certification supports safe installation in oil, gas, chemical processing, and other high-risk facilities.
Industries such as oil and gas, chemical processing, marine, and mining benefit from the 24" flexible length because it enables routing around equipment in tight spaces, reduces the need for extra fittings, and speeds up panel builds. It is particularly advantageous in confined installations where straight fittings would require excessive bends and labor.
Forged brass offers excellent mechanical strength and corrosion resistance, improving durability in harsh environments like chemical plants and offshore facilities. This material choice reduces maintenance frequency and extends service life, making the ECLK624 a cost-effective choice for long-term hazardous-area installations.
The 24" flexible length, dual-end connection, and 2" trade size simplify procurement and field assembly, shrinking installation time and labor costs. Its robust forged brass construction and NEC/CEC compliance reduce maintenance needs and risk of non-conformance, delivering a lower total cost of ownership over the life of the installation.
