Samsung front loading washing machine door seal boot DC64-00802A diaphragm, and DC97-04973B Assembly Wire Diaphragm. Both brand new and genuine Samsung.
Bought for my Samsung WF328AAW/XAA (and have installed several of exactly the same in the past), but just replaced that washer.
fits several other models (check Amazon, Samsung, Appliance Parts Pros, etc. for others).
