Quick Summary

ECGJH121 S516 coupling is a rugged hazardous-area connection designed for long, flexible runs in industrial installations. A common pain point is fittings that crack or seize under vibration, moisture, or chemical exposure, leading to costly downtime and rework. This ECGJH121 S516 delivers reliability with IP66 ingress protection and certifications under NEC/CEC as well as IECEx/ATEX for use in hazardous locations, supporting Class I, II, and III environments. The stainless-steel body, 21-inch flexible length, and 1/2-inch trade size optimize installation speed, durability, and ease of field adjustments, while reducing maintenance cycles. For procurement, it aligns with Crouse-Hinds explosion-proof couplings, enabling safe, compliant extensions in hazardous-area conduit networks.

The ECGJH121 S516 coupling features a 21-inch flexible length with male connections at both ends, enabling smoother routing through cramped or vibration-prone installations and reducing the number of joints required in long conduit runs. This translates to faster field assembly, lower labor costs, and greater reliability in dynamic environments such as offshore platforms or manufacturing floors. The stainless-steel construction provides excellent corrosion resistance, particularly in chemical plants and coastal facilities, reducing replacement cycles and maintenance overhead. Its IP66 rating protects against dust ingress and powerful water jets, supporting uptime in harsh weather or wash-down operations. Certified for NEC/CEC and IECEx/ATEX, the coupling ensures compliance across multiple regulatory regimes, simplifying cross-border projects and audits. Compatibility with the ECGJH family streamlines procurement and spare-parts inventory, while the 1/2-inch trade size fits standard conduit fittings for quick installation and long-term sustainability.

FAQs

When installing ECGJH121 S516 in hazardous locations, ensure proper alignment of the 21-inch flexible section to minimize bending stress and avoid sharp bends. Use appropriate seals and gaskets, verify IP66 integrity after assembly, and follow NEC/CEC IECEx/ATEX guidelines. The male-male ends simplify field assembly, reducing the number of joints and potential leak paths while maintaining a robust, compliant connection.
ECGJH121 S516 provides explosion-proof performance with IP66 ingress protection, supporting Class I, Division 1 (as well as Class II/III) locations. The stainless-steel construction resists corrosion, while the 1/2" trade size and 21" flexible length enable reliable conduit routing in challenging zones. This combination reduces downtime and ensures regulatory compliance across approved hazardous-location applications.
Yes. ECGJH121 S516 is designed to integrate with the Crouse-Hinds ECGJH family of explosion-proof couplings. Its 1/2" trade size and male-to-male configuration provide straightforward compatibility with standard conduit components, allowing quick extensions or repairs without custom adapters. This compatibility simplifies stocking, maintenance, and future upgrades in hazardous-area networks.
Certification documentation includes NEC/CEC compliance, IECEx/ATEX considerations, and Canadian certification pages for explosion-proof conduit fittings. An EU declaration of conformity and UL/CSA-type approvals are available as part of the installation and compliance package. These documents facilitate cross-border projects and ensure the product meets regional hazardous-location requirements.
The combination of corrosion-resistant stainless steel and IP66 protection reduces maintenance cycles and part replacements, delivering lower lifecycle costs. Quick installation with a 21-inch flexible length minimizes field labor time, while the 1/2-inch trade size aligns with common fittings, reducing inventory needs. Overall, expect improved uptime, safer operations, and faster project completion with reduced total cost of ownership.
