FAQs
Yes. XJ128 HDG is specified for a 5 in trade size and rigid/IMC conduit, designed to retrofit into current installations without extensive rework. It integrates with the XJG expansion coupling family, reducing the need for adapters and simplifying field assembly while maintaining NEC/CEC compliance.
The XJ128 HDG supports up to 8 inches of conduit movement, compensating for thermal expansion and mechanical shifts. It is fabricated from steel with a hot-dip galvanized finish to maximize corrosion resistance in ordinary/non-hazardous locations, aligning with UL and NEC/CEC standards for robust performance.
Yes, the hot-dip galvanized steel construction makes it well-suited for outdoor and damp environments often encountered in industrial facilities. It is intended for ordinary/non-hazardous locations per area classification and is compatible with standard rigid/IMC conduit systems, enhancing lifecycle reliability in challenging installations.
XJ128 HDG adheres to NEC/CEC standards, and UL certification is available for related XJG expansion couplings used with EMT and Rigid/IMC configurations. This combination offers regulatory assurance and industry-recognized safety validation for critical installations.
By using a durable hot-dip galvanized steel body and a compatible 5 in/8 in movement design, maintenance intervals extend and downtime decreases. Integration with the XJG family simplifies procurement and installation, delivering faster project completion and long-term lifecycle savings through reduced repair frequency and fewer field adjustments.
