XJG-EMT Conduit Expansion
Joints With Internal Grounding
For EMT Conduit
Application:
XJG expansion couplings are used with EMT
Conduit:
ɀ without the need for an external bonding
jumper and clamps
ɀ to couple together two (2) sections of
conduit subject to longitudinal movement
ɀ in long conduit runs to permit linear
movement caused by thermal expansion and
contraction.
ɀ on long conduit runs to prevent conduit
from buckling and ensuing circuit failures
ɀ indoors or outdoors where conduit
expansion occurs and there are wide
temperature ranges
ɀ in conduit runs that cross structural joints
ɀ in conduit runs to prevent damage to
conduit supports such as in a building or on
a bridge
ɀ with optional redundant visible
grounding strap
