Product review (3 stars): Do not order this part by itself, buy the upper seal at the same time
If you replace only the lower seal, you'll have to buy the high temperature glue separately (at basically the same price that you'd pay for the upper seal with the glue).  I had already replaced the upper seal the prior week and luckily had retained the leftover high temperature glue so I could finish the repair, otherwise I'd be on the hunt for the glue needed to install this.  The installation is time is roughly the same for changing both as opposed to just the lower seal, most of the effort is in getting the front of the dryer apart to expose the seals.
