Eaton ECGJH312 Coupling - 12" Flexible, Class I Division 1
Part Number: ECGJH312
Quick Summary
ECGJH312 coupling is a flexible conduit connection that delivers reliable, quick-assembly electrical paths in hazardous-area installations. In demanding environments, rigid fittings can fail from vibration or misalignment, leading to downtime and maintenance headaches. It supports NEC/CEC compliance and is rated for Hazardous/Classified Locations with Class I, Division 1 service, backed by Canadian UL certification and an EU declaration of conformity. Designed for compatibility with standard conduit systems, the forged brass body, 1" trade size, and 12" flexible length enable faster, safer installs while reducing long-term maintenance costs. This combination also supports faster field deployments, safer operations, and simplified spare-part stocking for maintenance teams.

Eaton Specification Sheet - ECGJH312
Feature: 12 inch flexible length enables routing in tight spaces and dampens vibration, reducing conduit stress. Business Impact: Enhances installation speed and longevity of connections, lowering maintenance intervals and downtime in demanding environments. Application: Chemical plants, offshore platforms, and equipment rooms where space is constrained. Feature: Male connections on both ends simplify field assembly by removing the need for adapter fittings, shortening installation time. Business Impact: Improves crew efficiency, reduces potential leak paths, and accelerates commissioning. Application: Standard conduit runs requiring direct coupling between segments. Feature: Forged brass construction delivers robust corrosion resistance in corrosive and humid hazardous areas. Business Impact: Extends service life, lowers replacement costs, and improves reliability in harsh atmospheres. Application: Chemical processing, marine/rig installations, and other hazardous-location facilities. Feature: 1" trade size ensures compatibility with common conduit systems and fittings, streamlining stocking and procurement. Business Impact: Reduces part diversity and inventory costs, while ensuring consistent performance. Application: Typical 1" conduit networks in industrial plants. Feature: NEC/CEC compliance and Hazardous Location ratings (Class I, Division 1) provide regulatory alignment and safer operation. Business Impact: Minimizes compliance risk, supports safer commissioning, and aids in audit readiness. Application: Any installation requiring formal safety classifications and certified performance. Insight: Field teams benefit from a proven, plug-and-play solution that matches standard conduit practices, while procurement gains from consistent availability and documented specifications.
