FAQs
ECGJH121 S758 is designed for Class I, Division 1 environments and NEC/CEC compliance. When installing, verify correct conduit routing to minimize bending stress, follow the 21" flexible length guidance, and ensure male-end connections are fully engaged. The rugged forged brass and PVC coating resist abrasion and moisture, reducing maintenance needs.
This coupling carries NEC/CEC compliance and NEC hazardous ratings for Class I, Division 1, along with Class II, Division 1 and Class III. Area classification is Hazardous/Classified Locations, making it suitable for explosion-protected installations. Always reference the installation instructions and local codes to confirm suitability for your specific hazardous location.
Yes. The ECGJH121 S758 is a 1/2" trade size coupling with male connections on both ends, designed to join standard conduit runs. Its forged brass body and PVC coating support reliable field connections, while the 24.75" overall length accommodates longer routing with a 21" flexible segment for easier alignment.
The flexible PVC protective coating shields the brass core from abrasion, moisture ingress, and chemical exposure common in hazardous locations. This coating extends service life, reduces corrosion-related failures, and lowers preventive maintenance intervals without compromising electrical performance or ease of installation.
Using ECGJH121 S758 can shorten installation time due to its flexible length and simple male-end connections, lowering labor costs. Its corrosion-resistant materials and protective coating reduce replacement frequency, delivering lower total cost of ownership in harsh environments and improving system uptime for mission-critical equipment.
