Eaton Crouse-Hinds ECGJH121 Coupling - Hazardous Locations
Part Number: ECGJH121
Quick Summary
ECGJH121 coupling provides a 21-inch flexible, forged-brass connection for hazardous-location conduit systems in industrial plants. Sourcing reliable, certified fittings that withstand vibration, temperature swings, and corrosive exposures in these environments is a common procurement challenge. It carries NEC/CEC compliance and hazardous ratings for Class I, Division 1; Class II, Division 1; and Class III, enabling safe use in explosive atmospheres. The design aligns with a 1/2 inch trade size and a 21 inch flexible length, reducing installation time and the need for multiple parts. In practice, this means fewer field failures, lower maintenance costs, and smoother project commissioning for end users in oil, gas, chemical, and marine applications.

FAQs
ECGJH121 uses male connections on both ends and a 1/2 inch trade size, designed to mate with standard EC series conduit fittings. It fits NEC/CEC compliant hazloc systems, simplifying integration with existing conduits and reducing the need for adapters.
The 21-inch flexible length accommodates routing around obstacles and through confined areas, reducing the number of additional fittings. This saves installation time, lowers inventory, and minimizes potential leak points in hazardous environments.
Yes. ECGJH121 is rated for NEC hazardous locations with Class I Division 1, along with Class II Division 1 and Class III ratings, making it appropriate for refineries, chemical plants, and similar hazloc applications.
ECGJH121 carries NEC/CEC compliance and hazardous-location ratings. Additional certification documents from Eaton and UL/Canada declarations are available to verify conformance for hazardous-area installations.
The forged brass construction resists corrosion, extending service life. Fewer fittings and faster installs reduce labor costs, spare parts, and downtime, delivering tangible ROI in ongoing maintenance-heavy facilities.
