Product review (5 stars): allowing me to find the best price. This $20
Fits my KitchenAid KUDI01ILBL6 perfectly; seemed a little lightweight at first but has a snug fit and tight seal with door. Take old one off when you have new one in hand to compare direction and placement of ribs and small flange. I used no glue and it is holding securely, then it can be popped out and cleaned out when necessary.  Lots of cross referencing of part numbers from Kitchen Aid site, Easyapplianceparts.com and PartsDr.com, so I found this gasket sold as 12 different part numbers, allowing me to find the best price. This $20.32 price was great!
