Technical Specifications

This ECGJH coupling features 1/2-inch trade size with male threaded connections on both ends, constructed from forged brass for maximum durability. The 12-inch flexible length provides excellent vibration isolation while maintaining Class I, Division 1 hazardous location rating. Dimensions measure 1.5 inches in height and width with 15.75 inches total length, weighing 1.65 pounds for substantial construction. NEC/CEC compliant design ensures code compliance in all North American installations.

Installation Process

1. Verify hazardous area classification matches coupling rating before installation
2. Thread male end onto equipment connection or conduit fitting using appropriate thread compound
3. Hand tighten connection, then use wrenches to achieve proper torque without over-tightening
4. Connect opposite male end to conduit system or additional fitting
5. Ensure flexible section is properly supported to prevent excessive stress
6. Verify all connections are secure and maintain explosion-proof integrity

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
• Oil and Gas Operations - Drilling platforms, pumping stations, and pipeline facilities
• Paint and Coating Operations - Spray booths, mixing rooms, and solvent storage areas
• Grain Handling Facilities - Elevators, mills, and processing equipment with combustible dust
• Aircraft Hangars - Maintenance areas and fuel handling systems
• Marine Applications - Ship engine rooms and fuel systems in hazardous zones
• Manufacturing Plants - Areas with flammable vapors from industrial processes
• Equipment Connections - Motor control centers, switchgear, and instrumentation in classified areas

Flexible Coupling System Benefits

Flexible couplings provide critical advantages over rigid conduit connections in hazardous locations by absorbing vibration and thermal expansion while maintaining explosion-proof integrity. The flexible design prevents stress concentration that can compromise threaded connections and allows for easier equipment maintenance without disturbing the entire conduit system. This reduces long-term maintenance costs and improves system reliability in critical safety applications.

Why Choose Forged Brass Construction?

Forged brass offers superior performance compared to cast alternatives through enhanced mechanical properties and corrosion resistance. The forging process creates a denser, stronger material structure that withstands the demanding conditions of hazardous location installations. Brass naturally resists corrosion from industrial chemicals and marine environments while providing non-sparking safety characteristics essential for explosive atmosphere applications. This premium material choice ensures decades of reliable service in the most challenging electrical environments.
