Eaton Crouse-Hinds XJG34 EMT expansion coupling - NEC/CEC
Part Number: XJG34 EMT
Quick Summary
XJG34 EMT expansion coupling is a steel expansion and deflection device for EMT conduit used in industrial electrical installations. It helps prevent stress and misalignment when runs experience movement from vibration or thermal expansion. For engineers facing tight spaces or frequent equipment motion, the coupling provides reliable compensation without compromising enclosure integrity. It complies with NEC/CEC standards and is suitable for Ordinary/Non-Hazardous Locations, supporting factory floors, control panels, and distribution enclosures. By standardizing on this Eaton Crouse-Hinds part, procurement gains a consistent footprint and easier stocking, while maintenance teams benefit from simplified replacement and reduced downtime. This fits well with common EMT conduit accessories and other Crouse-Hinds fittings, reinforcing a cohesive, standards-aligned installation approach.
