XD deflection couplings from Eaton's Crouse-Hinds Division can be installed indoors, outdoors, buried underground or embedded in concrete in non-hazardous areas. XDs provide a flexible and watertight connection for protection of conduit wiring systems from damage due to movement. They are used with standard rigid conduit or PVC rigid conduit (PVC requires rigid metal conduit nipples and rigid metal-to-PVC conduit adapters). XDs are also available with a hot dip galvanized finish for added corrosion protection against harsh environmental factors. Typical applications for XD deflection couplings include underground conduit feeder runs, runs between sections of concrete subject to relative movement, runs between fixed structures, conduit entrances in high rise buildings, bridges, marinas, docks and piers.
