Eaton Specification Sheet - ECGJH621
The ECGJH621 offers a 21-inch flexible length with male connections at both ends, enabling easier routing around obstacles and tight bends. This design reduces field time, minimizes misalignment, and lowers labor costs while ensuring reliable seals in hazardous environments. It is ideal for long conduit runs in chemical plants and offshore platforms where space is constrained. Forged brass construction delivers corrosion resistance and rugged durability, extending service life and reducing maintenance costs in harsh industrial settings. The 2-inch trade size standardizes with common conduit systems, simplifying sourcing and inventory management for retrofit and new-build projects. With a total length of 27.5 inches and a compact 4.25 inch profile, the assembly remains stable under vibration and thermal cycling in demanding conditions. Documentation and installation guides speed approvals and ensure code-compliant field work.
