Eaton Specification Sheet - ECGJH521 S758
The ECGJH521 S758 features a 21 inch flexible length, enabling easier routing around heavy equipment and tight spaces, which reduces the number of extra fittings and saves installation time in hazardous-area runs. This translates to measurable improvements in field productivity and lower total installed cost for explosion-proof conduit systems. The male connections at both ends simplify field assembly and reduce alignment errors, boosting reliability in demanding environments such as chemical plants and offshore facilities. Forged brass construction delivers robust mechanical strength and corrosion resistance, extending service life in harsh industrial conditions while maintaining a compact profile. A flexible PVC protective coating protects the coupling from abrasion and moisture ingress, supporting long-term performance in marine and damp facilities and lowering maintenance costs. The 1-1/2 inch trade size standardizes compatibility with existing conduit infrastructure, streamlining retrofit projects and future scalability in plant upgrades. Together with NEC/CEC compliance and the Class I Division 1 rating, ECGJH521 S758 offers a proven, maintenance-friendly solution for hazardous-location installations.
