FAQs
The ECLK418 is designed for hazardous and classified locations (Class I, Division 1; Class II Division 1; Class III) and is NEC/CEC compliant. It uses a forged brass construction with an 18-inch flexible length and 1-1/4 inch trade size to connect conduit runs in industrial and marine environments while meeting rigorous explosionproof requirements.
The 18-inch flexible section allows for easier alignment across misaligned or obstructed pathways, reducing the need for additional fittings. This lowers labor time, minimizes potential leak points, and improves overall system reliability in tight or irregular spaces typical of hazardous-area installations.
Yes. The ECLK418 supports a 1-1/4 inch trade size with male connection on one end and female connection on the other. This configuration simplifies field assembly, eliminates extra adapters, and enables quick integration into existing conduit networks in hazardous locations.
ECLK418 adheres to NEC/CEC standards and is rated for Hazardous/Classified Locations, including Class I Division 1, Class II Division 1, and Class III environments. It is UL-certified for EC explosionproof performance, which supports formal safety approvals, audits, and compliant procurement in North American facilities.
Durable forged brass construction provides corrosion resistance and reduced wear, extending service life in harsh environments. The integrated male-female design minimizes field fittings, lowering maintenance frequency and labor costs. In turn, this contributes to a lower total cost of ownership for hazardous-area conduit networks.
