Abstract
An air duct includes a rigid thermoplastic body having softer elastomeric cuff members welded to the ends thereof. The cuff members comprise an outer sealing component and a weldable insert bonded to at least a portion of the inner surface. The cuff members are adhered to the thermoplastic body at the weldable insert through a spin welding or other suitable welding process. The chemical compatibility between the insert and the thermoplastic body provides a robust weld at the interface.
