official hvac seal replacement thread?

[Pete M]

do we have one?  I know I've seen guys do it, but can't find one.  I figure we really should have one in the DIY section so it's searchable.  that foam isn't getting any younger.

I bought my stuff from Grainger.  You can get both open cell and closed cell foam in various thicknesses and then cut to shape with a knife or scissors.

 

The downside is that the stuff is not cheap.   But....it does do the job as well as OEM, and since OEM is no longer available, it's about the only solution.   I have  few pictures of what I did, if I search around for them.
