XD Expansion/Deflection Coupling - Watertight, Corrosion-Resistant
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.
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
