Product review (5 stars): Never give up.
This seal did not fit our dryer.  Nevertheless we found a way to reach satisfaction.  What is with these manufacturers and their meaningless part numbers???  I did a lot of research to find the correct match, and get enough indications that it should match perfectly.  Then I had to basically do open-heart surgery on our dryer to completely remove the dryer drum.  Fortunately there are some helpful You-tube videos with advice how to do that.  Then we glued on the new seal onto the rim of the drum and were alarmed to see that it was too big.  So much for the supposed perfect fit.  We carefully trimmed off the excess with a utility knife, reducing the circumference by about an inch.  I have been on guard that cutting the continuous circle and joining the edges would leave an edge that would cause friction and failure.  If so, I will choose to get a new dryer instead.  But it has worked reliably for about 2 months now.  So far, so good, and much cheaper than a new dryer would be.
