Product review (4 stars): Works fine for Kenmore Series 90...
Ordered for my Kenmore Series 90.  My front felt had split completely around so I ordered 2 since I was going to have the drum out anyway.  At the time of ordering, the picture was just the tube of glue but does come with glue and one felt seal.

I removed the remnants of the old front seal (putty knife and some a little scraping) first.  Out of the package, the seal looks like it's too small, and if you eyeball it you'll be convinced it's not the right size. It does have a little give, but I had my doubts.  So I first stretched the seal around the drum, using several spring clamps to hold in place and working my way around from one side to the other.  It was snug but fit.  I took it off, and as recommended, applied the glue first to the drum and then wrestled the seal on.  Got a little messy and seemed more trouble than it should have been.

For the rear seal, after cleaning off the old one, I put the new one on dry like the first.  I then ran around the perimeter, lifting up on the seal and squeezing the glue underneath.  For me this worked a lot better and with no mess.  But this may be due to all the clamps I used and making sure I pulled down and away to open up just enough space for the tube nozzle (which is long enough to allow for application like this).

2 months later, things are all still well.  The glue does set up fairly quickly, so be ready to go in one shot and extra pair of hands (or clamps) are a good idea if available.
