XD Expansion/Deflection
Coupling
Application:
XD couplings can be installed indoors,
outdoors, buried underground, or embedded
in concrete in non-hazardous areas. XD’s are
used with standard rigid conduit or PVC rigid
conduit. (PVC requires rigid metal conduit
nipples and rigid metal-to-PVC conduit
adapters.) XD’s provide a flexible and
watertight connection for protection of
conduit wiring systems from damage due to
movement.
Typical applications include:
ɀ Underground conduit feeder runs
ɀ Runs between sections of concrete subject
to relative movement
ɀ Runs between fixed structures
ɀ Conduit entrances in high-rise buildings
ɀ Bridges
ɀ Marinas, docks, piers
Features:
ɀ XD couplings accommodate the following
movements without collapsing or fracturing
the conduit, and damaging the wires it
contains:
1. Axial expansion or contraction up to
2. Angular misalignment of the axes of the
coupled conduit runs in any direction to 30°
3. Parallel misalignment of the axes of
coupled conduit runs in any direction to
ɀ Inner sleeve maintains constant I.D. in any
position and provides a smooth insulated
wireway for protection of wire insulation
ɀ Watertight flexible neoprene outer jacket is
corrosion resistant and protects the
grounding strap and the attachment points of
the hubs
ɀ Tinned copper flexible braid grounding
straps assure grounding continuity
ɀ Stainless steel jacket clamps for strength
and corrosion resistance
ɀ Standard tapered electrical threads fit
standard rigid conduit
ɀ Integral hub bushing protects insulation of
conductors
Standard Materials:
ɀ Hubs –
ɀ Outer jacket – molded neoprene
ɀ Jacket clamps – stainless steel
ɀ Inner sleeve – molded plastic
ɀ Grounding straps – tinned copper flexible
braid
