FAQs
The ECLK412 uses a 12 inch flexible length with a male end on one side and a female end on the other, allowing quick alignment and secure seals even in restricted enclosures. This minimizes adjustment time and reduces risk of misalignment during field assembly, which translates to faster commissioning and lower labor costs on hazardous-area projects.
ECLK412 is certified under NEC/CEC standards and rated for Class I, Division 1 hazardous locations, with additional Class II and Class III ratings. This ensures compliance for explosive atmospheres and supports regulatory approval across North American facilities, offshore platforms, and chemical processing plants.
Yes. The ECLK412 is designed for a 1-1/4 inch trade size and features male and female ends to simplify direct connections with standard conduit fittings. This compatibility reduces the need for adapters, simplifies procurement, and accelerates installation in new builds or retrofit projects.
Forged brass provides superior corrosion resistance and durability, lowering maintenance frequency in harsh environments such as chemical plants or offshore facilities. The robust construction supports extended service life, fewer field replacements, and lower total cost of ownership over the equipment lifecycle.
Yes, the ECLK412 is suitable for hazardous locations commonly found in offshore and marine applications. Its hazardous area certification, durable brass material, and rated compatibility with standard conduit fittings mean it can perform reliably in challenging weather, splash exposure, and temperature variations typical of such environments.
