XJG Expansion Couplings

XJG Expansion Couplings for Rigid Conduit The XJG Expansion Couplings by Thomas & Betts are designed to allow for the contraction and expansion of conduit runs without compromising the mechanical or bonding integrity of the raceway. These couplings provide a raintight, flexible connection suitable for rigid steel or intermediate metal conduit applications, ensuring electrical continuity through an internal bonding jumper. Ideal for electrical distributors and switchgear suppliers managing conduit systems requiring thermal expansion accommodation. Specifications Size: 3 Inch Movement: 8 Inch Length: 16.12 in Outside Diameter: 4.96 in Material: Malleable Iron Product Weight: 18.7 lbs Manufacturer: Thomas & Betts Manufacturer Part #: XJG88-TB Application: Allows for the contraction and expansion of a conduit run without reducing the mechanical or bonding integrity of the raceway Features Body constructed of malleable iron with zinc plating and aluminum acrylic paint for corrosion protection Internal bonding jumper made of tinned copper braid to meet UL fault current test requirements and comply with bonding codes No disassembly required during installation, simplifying and speeding up the process PTFE/Synthetic fiber packing material (Teflon® coated) creates a raintight seal around the conduit Designed to maintain electrical continuity without the need for external bonding jumpers Suitable for use in electrical conduit systems requiring thermal expansion and contraction compensation Downloads & Links Technical Drawing / Spec Sheet Canada Technical Drawing / Spec Sheet US Spec Sheet Instruction Sheet
