The XJG84 HDG expansion coupling is designed to absorb up to 4 inches of conduit movement in a 3-inch trade-size system, which translates directly into reduced thermal stress and fewer field adjustments on long, exposed runs. This feature improves system reliability and minimizes downtime during temperature swings or seismic events, supporting safer startup and ongoing operation in manufacturing environments. Constructed from steel with a hot-dip galvanized finish, the unit resists corrosion in damp, outdoor, or washdown zones, delivering lower maintenance costs over its service life. Its rigid/IMC conduit compatibility ensures straightforward integration with existing rigid conduit networks, simplifying material lists and project timelines. NEC/CEC compliance alongside UL certification for EMT and Rigid/IMC installations provides a clear regulatory path for code approvals and inspection readiness, reducing project risk. The 10.25 in length and 5.37 in width/height footprint balance robust protection with space-efficient installation in service corridors and equipment pads. Industry guidance sheets and installation references, such as IF 1508 for assembly-free XJG, support faster field assembly and consistent quality control on-site.

FAQs
For installation, ensure the 3 inch trade-size conduit aligns with the XJG84 HDG’s expansion capability, allowing up to 4 inches of movement along the run. Use compatible rigid/IMC fittings and follow NEC/CEC guidelines. The 10.25 inch length and 5.37 inch width/height fit standard service space, and UL/NEC/CEC certifications support compliance documentation during audits.
Yes. It features a steel body with a hot-dip galvanized finish, which provides corrosion resistance in damp, outdoor, and washdown environments. It is rated for ordinary/non-hazardous locations and is designed to integrate with standard rigid/IMC conduit runs, improving longevity even in exposed facilities.
The XJG84 HDG expansion coupling complies with NEC/CEC standards and is UL-listed for EMT and Rigid/IMC installations. These certifications support code-compliant installations, facilitate procurement documentation, and reduce the risk of non-conformance during project reviews in industrial facilities.
The unit provides a 10.25 inch length, 5.37 inch height, and 5.37 inch width, with a weight of 13.8 pounds. It supports 3 inch trade-size conduit and up to 4 inches of movement, balancing robust protection with feasible space requirements on typical equipment pads and in utility corridors.
The expansion coupling’s ability to accommodate movement reduces field rework caused by thermal expansion and deflection, shortening installation times and lowering commissioning risks. The hot-dip galvanized finish extends service life in harsh environments, lowering maintenance intervals. Availability of installation guidance like IF 1508 helps ensure assembly-free, consistent field installation across projects.
