FAQs

ECGJH321 S516 is designed for 1 inch trade size conduit systems and features male connections on both ends for straightforward mating with compatible Eaton Crouse-Hinds fittings. Its stainless steel construction and IP66 rating ensure reliability in hazardous locations, while the 21 inch length accommodates routing around equipment without excessive joints.
Before installation, verify power is off and the site is properly classified. Align conduits with the male ends, tighten to manufacturer torque specs, and use appropriate seals and gaskets to maintain IP66 integrity. Ensure the assembly is secured away from moving parts and tested for ingress protection after installation to verify compliance.
ECGJH321 S516 carries NEC/CEC IECEx/ATEX certifications for hazardous areas, IP66 ingress protection, and NEC hazardous ratings of Class I, Division 1; Class II, Division 1; Class III. These certifications support compliance across global sites, including oil/gas, chemical processing, and marine installations.
Yes. The 21" flexible length reduces the number of fittings and joints, while stainless steel offers superior corrosion resistance. Quick, secure connections minimize field labor, and robust sealing lowers the risk of water or dust ingress, contributing to longer service intervals and lower maintenance costs in harsh environments.
