Cooper Crouse-Hinds Expansion and Deflection Joints and Couplings are available from KSCdirect:

XD Expansion/Deflection Coupling
- Watertight, Corrosion-Resistant

00172to00175.jpgApplication: 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.

Features:
• 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 3⁄4″
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 3⁄4
• Inner sleeve maintains constant I.D. in any position and provides a smooth insulated wireway for protection of wire insulation
• Watertight flexible neoprene outer jacket is corrosion resistant and protects the
grounding strap and the attachment points of the hubs
• Tinned copper flexible braid grounding straps assure grounding continuity
• Stainless steel jacket clamps for strength and corrosion resistance
• Standard tapered electrical threads fit standard rigid conduit
• Integral hub bushing protects insulation of conductors

XJG Conduit Expansion Joints With Internal Grounding For Rigid Metal Conduit and IMC - Wet Locations

00172to001751.jpg

• Without the need for an external bonding jumper and clamps (up to 4″)
• 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 buckling and ensuing circuit failures • Indoors or outdoors 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 or on a bridge
• With optional redundant visible grounding strap

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

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 buckling and ensuing circuit failures
• Indoors or outdoors 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 or on
a bridge
• With optional redundant visible grounding strap

XJGD Combination Expansion/Deflection Coupling and Expansion Joint Internally Grounded

00172to001753.jpg

XJGD combination fittings are used with rigid metal conduit and IMC:
• To accommodate axial expansion, angular misalignment and parallel misalignment
• To couple together two (2) sections of conduit subject to longitudinal movement
• To maintain a ground connection without the need for an external bonding jumper and clamps
• In long conduit runs to prevent conduit from buckling and causing circuit failures
• Indoors or outdoors where conduit expansion occurs and there are wide temperature swings
• In conduit runs that cross structural joints
• In conduit runs to prevent damage to conduit supports such as in a building or on a bridge
