Eaton Crouse-Hinds XJG34 Expansion Coupling - NEC/CEC
Part Number: XJG34
Quick Summary
XJG34 expansion coupling by Eaton Crouse-Hinds provides adjustable conduit movement for rigid/IMC systems. In busy facilities, misalignment and stress from thermal expansion can derail schedules and shorten conduit life. It is designed for ordinary/non-hazardous locations and carries NEC/CEC compliance with UL Canada certification support, giving engineers confidence in code-adherent installations. By simplifying installation and ensuring durable performance, it reduces downtime, lowers maintenance costs, and supports reliable, compliant enclosures in automation environments. Compatible with standard installation accessories, it helps maintain alignment across panel interfaces and equipment cabinets. From a procurement perspective, the XJG34 reduces part variety and speeds up sourcing for 1" rigid/IMC conduits.

Movement tolerance and size are optimized for 1" trade size rigid/IMC conduits, delivering up to 4" of movement. This capability absorbs expansion, contraction, and vibration across equipment racks and cabinet interfaces, significantly reducing field repairs, misaligned connections, and early wear. Compatibility with standard installation accessories—such as mounting brackets and gaskets—ensures fast, safe connections in tight panel interfaces and crowded cable trays. Material and durability: The steel housing provides sturdy protection against impact, corrosion risk in typical factory environments, and repeated flexing from machinery movement. It delivers excellent long-term reliability, minimizes maintenance cycles, and extends service life in ordinary/non-hazardous locations where rugged fittings are routinely required. The rugged construction pairs with common conduit fittings and factory-installed accessories to streamline field installation and reduce inventory complexity. Code compliance: NEC/CEC standards and area classification specify ordinary/non-hazardous locations, ensuring installations meet electrical codes. This combination supports safe, code-compliant installations, reduces compliance risk, and speeds inspection processes during commissioning. UL Canada certification references validate performance in cross-border projects, reinforcing procurement confidence and easing regulatory approvals on industrial sites. Physical footprint: 8.3 in length, 3.4 in height, 5.1 in width, and 2.4 lb weight define a compact, yet robust, solution. The compact form minimizes clearance needs and helps sequence wiring in crowded panels, while maintaining sufficient reach for movement. This size profile enables easier handling during installation and reduces freight and storage costs across maintenance cycles. Documentation and resources: Access installation instructions IF 343, catalogs, spec guides, and safety certifications from Eaton to support a fast, error-free deployment. This repository accelerates design reviews, decreases misinterpretation, and helps ensure consistent field practices across multiple projects. Use the downloadable assets to validate compatibility before purchasing, speeding procurement and reducing project risk.

FAQs
XJG34 installs by securing the expansion coupling between rigid/IMC sections using standard mounting hardware and the 1 inch trade-size threads. Follow IF 343 installation instructions for proper joint alignment, torque recommendations, and deflection limits. Ensure support brackets are used to maintain position, and verify movement capacity of 4 inches before final tightening. Inspect for clean mating surfaces and proper gasket seating to ensure a leak-free, code-compliant joint.
XJG34 uses a steel body designed to resist repeated flexing and vibration. Its 4 inch movement capacity accommodates expansion and contraction without overstressing the conduit, reducing joint fatigue and wear. The coupling’s rigid/IMC compatibility ensures stable electrical continuity in automated systems, even under fluctuating plant temperatures. Field service data show consistent performance with standard mounting practices and accessories.
Yes. XJG34 is specified for NEC/CEC standards and ordinary/non-hazardous area classifications, supporting safe, code-compliant installations. It aligns with Canadian certification requirements and UL Canada verifications, aiding cross-border projects. When used with proper accessories and correct installation practices, it helps meet regulatory expectations during inspections and commissioning.
XJG34 is ideal for expansion and deflection needs in automation panels, motor control centers, and instrument enclosures using 1" rigid/IMC conduit. It mitigates stress from thermal and mechanical movement, maintains conductor alignment, and simplifies routing in compact cabinets. Its 8.3" length and 2.4 lb weight make it practical for retrofit and new-build installations in manufacturing environments.
Official resources include IF 343 installation sheets, expansion-deflection spec guides, brochures, and catalog pages. Download these from Eaton's site or the AutomationDatabase product page to confirm dimensions, movement limits, and compatibility. These documents reduce guesswork, streamline ordering, and support accurate field fabrication and commissioning, improving project timelines and total cost of ownership.
