This is a brand new coupler to replace your worn out one in your KitchenAid Blender. Fits all colors and configurations of the following models: KSB3 KSB5 Note that this will fit your blender if it begins with either "KSB3" or "KSB5". Most blender models will be something like "KSB3WH" or "KSB5OB1" where the last 2-3 letters only determine the color of the blender, which is not important for determining fit of this part.
List Price was $8.60, now it's just $0.10
That is very noce of you to list. I wonder if a change in title might help folks who could use this item actually open the post.
