This is a genuine manufacturer sourced replacement part used on Waring blenders. The coupling is the part of a blender that transfers power from the blender's motor to the blade assembly. Over time, the teeth on blender coupling wear down until they no longer engage properly on the blade assembly. It is made out of plastic and it is sold individually.
This is an authentic OEM sourced replacement blending assembly that is specially designed for use with Waring blenders. It is the main blade that cuts food inside the container. When replacing this assembly it is recommended to replace the gasket to ensure the proper seal, keep in mind the rubber gasket is sold separately. Please note this high quality item is sold individually.
