FAQs
The ECLK724 uses a standard 2-1/2 inch trade size and offers male one end and female one end connections, enabling straightforward integration with existing EC explosionproof fittings. Its stainless steel construction resists corrosion in harsh environments, while its 30 inch overall length and 24 inch flexible section accommodate longer runs and routing without compromising safety or performance in hazardous locations.
The coupling adheres to NEC/CEC requirements and carries NEC hazardous ratings for Class I, Division 1, as well as compatible ratings for Class II and Class III. It also holds Canadian certification for hazardous locations, providing cross-border regulatory confidence and streamlining procurement for North American projects in oil, gas, and chemical processing.
Yes. Its stainless steel construction, explosionproof design, and robust 30 inch length with a 24 inch flexible segment make it well-suited for offshore, marine, and other harsh-location applications. The product’s hazard-classifications and certifications ensure reliable performance under vibration, moisture, and corrosive exposure typical of marine environments.
Plan for the 2-1/2 inch trade size fittings and the 30 inch body with a 24 inch flexible portion to minimize joints and potential leak paths. Ensure proper torque on connections, verify compatibility with current EC explosionproof couplings, and confirm compliance with NEC/CEC requirements for Class I, Division 1 and related classifications in the target location.
The ECLK724 delivers long service life thanks to stainless steel construction, reducing corrosion-related replacements. Its 24 inch flexible segment and secure male/female ends simplify installations and maintenance, lowering downtime and labor costs. While upfront costs may be higher, regulatory compliance and durability translate to lower total cost of ownership in hazardous-area projects.
