3 Inch XJG Expansion Coupling (4 Inch Movement)

Plasti-Bond PVC coated XJG Expansion Couplings are used to couple together two sections of conduit that are subject to longitudinal movement, helping to prevent damage to conduit supports in dynamic environments such as buildings or bridges. These couplings are especially critical for long conduit runs—both indoors and outdoors—where thermal expansion and contraction can cause linear shifts. XJD Expansion Couplings play a vital role in conduit systems that cross structural joints or span extended distances, preventing buckling and reducing the risk of circuit failures.
