FAQs
To install the ECLK221 S758, begin by inspecting both ends for damage and confirm the 3/4 inch trade size matches your conduit. Use standard conduit fittings compatible with NEC/CEC Class I, Division 1 environments, lubricate as required, and secure with proper NPT seals. The female-to-male ends simplify field assembly, while the PVC coating protects the forged brass from corrosion in harsh sites.
The ECLK221 S758 carries NEC/CEC compliance with hazardous-location ratings including Class I, Division 1. It is designed for use in hazardous and classified locations, providing explosion-proof sufficiency for oil, gas, and chemical processing environments. This ensures regulatory alignment, supports audits, and minimizes rework due to non-compliant fittings.
Yes. The forged brass construction with a flexible PVC protective coating is well-suited for offshore and marine environments where corrosion resistance and robust sealing matter. The 21-inch flexible length and 3/4 inch trade size support complex routing in tight spaces, while the ECLK design maintains explosion-protected integrity across repeatedly damp or salt-laden conditions.
This coupling is listed for Hazardous/Classified Locations under NEC/CEC standards, with Class I, Division 1 ratings. It supports hazardous-area classifications typical in processing plants and marine facilities. For additional verification, Canadian certification documents are available, helping satisfy cross-border compliance requirements during audits and supplier qualification processes.
The flexible PVC coating and forged brass body provide superior corrosion resistance, reducing maintenance cycles in harsh environments. Its 21-inch length and 3/4 inch trade size enable fewer field fittings and faster commissioning, delivering lower lifecycle costs and quicker project ROI. The plug-and-play ends simplify replacements, minimizing downtime during routine inspections.
