ABB Thomas & Betts XJG48-TB Conduit Expansion Coupling, 1-1/4 In.

<h2>Overview</h2>
<p>The ABB Thomas & Betts XJG48-TB is a 1-1/4 inch conduit expansion coupling engineered for rigid and IMC conduit systems where thermal expansion and contraction must be accommodated. Built from zinc-plated malleable iron, this expansion coupling features an internal tinned copper braid bonding jumper that maintains continuous electrical continuity across the joint without the need for external grounding jumpers. The 8-inch movement range makes it suitable for long conduit runs exposed to significant temperature variation — common in industrial facilities, outdoor installations, and building rooftops.</p>
<p>The threaded connection type and PTFE/synthetic fiber packing provide a secure, weathertight seal. Meeting UL E23018 and CSA standards, the XJG48-TB is code-compliant for use in a wide range of commercial and industrial applications.</p>
