XJG-EMT Conduit Expansion Joints With Internal Grounding For EMT Conduit


Applications:
XJG expansion couplings are used with EMT Conduit:
Without the need for an external bonding jumper and clamps
To couple together two(2) sections of conduit subject to longitudinal movement
In long conduit runs to permit linear movement caused by thermal expansion and contraction
On long conduit runs to prevent conduit from bucking and ensuring circuit failures
Indoor and outdoor where conduit expansion occurs and there are wide temperature ranges
In conduit runs that cross structural joints
In conduit runs to prevent damage to conduit supports such as in a building on a bridge
With optional redundant visible grounding strap
