FAQs
The XJG108 HDG expansion coupling is designed for rigid/IMC conduit systems. It supports a 4 in trade size, making it compatible with standard steel conduit runs found in many industrial plants. For EMT systems, UL certification pages confirm cross-compatibility in mixed-install environments, but verify your exact configuration against the NEC/CEC guidelines for your project.
The coupling allows up to 8 inches of conduit movement, which minimizes in-field bending, deflection, and adjustment. This reduces the number of fittings required and speeds up installation, translating to fewer labor hours and less downtime during retrofit or expansion projects.
Recommended for ordinary/non-hazardous locations in industrial facilities, manufacturing plants, and commercial spaces. The hot-dip galvanized steel finish provides corrosion resistance beneficial in damp or outdoor environments, while the 4 inch trade size supports standard steel conduit layouts in typical plant installations.
It is UL-listed for EMT and Rigid/IMC installations and complies with NEC/CEC standards. The product is rated for ordinary/non-hazardous locations, aligning with typical industrial safety and compliance requirements. Always refer to the UL certification pages and NEC/CEC references for project-specific validation.
By delivering durable steel construction with a corrosion-resistant HDG finish and a simplified installation footprint, the coupling reduces maintenance cycles and rework. The 8 inch movement capability minimizes future expansion constraints, lowering lifecycle costs and improving project ROI through faster commissioning and fewer field failures.
