Overview
The Eaton ECGJH-125-12 flexible coupling is part of the Crouse-Hinds EC series explosionproof couplings engineered for Class I and Class II hazardous locations. With a 1-1/4″ trade size and 12″ flexible length, this coupling accommodates difficult bends and allows for vibration isolation in demanding industrial conduit systems.
Key Features
- Forged brass end fittings for corrosion resistance and durability
- Bronze braid covering with flexible brass inner core for maximum flex capability
- Threaded male connections on both ends for secure installation
- UL 1203 certified for explosionproof applications
- Rated for ambient temperatures between −20°C to +40°C
- No bonding jumpers required; metallic braid provides continuous electrical path
