I was not finding a lint duct seal for my model either. That’s why I made an account to ask this question.
I am replacing the seal that they are showing in the video that is the seal for the drum.
I need to also replace what the tech in the video calls “the blower seal” that to the touch feels like soft foam and is a black looking ring.
I spent too long looking for that part and thought this help site would be of help, but sadly your reply was not helpful, not to mention I asked my question twice. Maybe it was not seen those two times but it appears to me that my questions were ignored.
