Product review (5 stars): Used as replacement seals for Maytag Neptune MDE9700AYW
They work perfectly!  We used two (2) of these (one for the front and one for the rear of the drum) on our Maytag Neptune MDE9700AYW.  If you're looking for new seals for this dryer you will have discovered that it was actually made by Samsung under contract to Maytag, and they don't offer replacement felt seals; instead, they offered the entire drum assembly (over $200), but even that is no longer available.  We placed the drum rollers (all four (4) of them: Dryer Drum Roller Kit for Whirlpool, Maytag, Samsung, DC97-07523B, W10177428) and replaced the seals using these (Whirlpool 280140 Seal for Dryer).  Just remove the old seals, clean the surface using acetone (wear rubber gloves) - don't sand the drum or use any abrasive brushes or tools, and let the sealant completely cure overnight before using the dryer.
