FAQs
ECGJH421 S516 is designed with male connections on both ends and a 1-1/4 in trade size, enabling straightforward mating with common explosionproof conduit fittings. Its 21 in flexible length accommodates routes that would otherwise require extra elbows, while maintaining IP66 protection and NEC/CEC IECEx/ATEX compliance for reliable operation in hazardous locations.
The ECGJH421 S516 carries NEC/CEC and IECEx/ATEX certifications, confirming suitability for hazardous locations such as Class I, Division 1 and related classifications. It also meets IP66 ingress protection, ensuring resistance to dust and water. These certifications support compliance during audits and cross-border projects in oil & gas, chemical, and marine industries.
This coupling is well suited for oil and gas, chemical processing, mining, offshore and marine applications, and any installation requiring explosionproof, corrosion-resistant connectivity. The 21 in flexible length minimizes joins, while the stainless steel body withstands harsh environments, shortening installation time and reducing maintenance cycles in demanding facilities.
By meeting IP66, NEC/CEC, and IECEx/ATEX certifications, ECGJH421 S516 provides documented protection against ingress and multi-jurisdictional compliance. Its stainless steel build and 1-1/4 in trade size align with standard conduit fittings, simplifying procurement, traceability, and audit trails for hazardous-area installations.
The combination of corrosion-resistant stainless steel, a long flexible run, and fewer joints translates to lower maintenance costs and reduced downtime. Quick, reliable installation lowers labor costs, while the robust IP66 and hazardous-location certifications minimize risk of corrosion-driven failures, yielding a favorable total cost of ownership over the system’s life cycle.
