The Crouse-Hinds XJGD Combination Expansion/Deflection Couplings are designed for rigid metal conduit (RMC) and intermediate metal conduit (IMC) applications requiring both expansion and deflection movement.
Description
Applications
- Connects two conduit sections subject to longitudinal movement.
- Allows for axial expansion, angular misalignment, and parallel misalignment.
- Suitable for long conduit runs in buildings, bridges, and industrial environments.
- Prevents buckling and conduit failures caused by thermal expansion/contraction.
- Eliminates the need for external bonding jumpers and clamps while maintaining electrical continuity.
- Used in conduit runs that cross structural joints.
Key Features
- Weatherproof & corrosion-resistant – Approved for indoor and outdoor installations.
- Available in 1” to 4” trade sizes.
- Allows 4” maximum conduit movement.
- Combines XD & XJG features:
- XD Component: Accommodates axial expansion (¾”), angular misalignment (30°), and parallel misalignment (¾”).
- XJG Component: Includes internal bonding springs and metallic bushings, ensuring ground integrity without external jumpers.
- Flexible neoprene outer jacket protects against moisture and corrosion.
- Stainless steel jacket clamps enhance structural strength.
- UL 514B & CSA 22.2 No. 18 3-12 certified for wet locations.
- Standard NPT threads fit rigid conduit connections.
- Optional bonding jumper (BJ Series) ensures redundant electrical grounding.
