Does anyone know what material can be used to replicate the existing (and deteriorating) blend door gasket material on the heater box? I have not found anything thin enough at the hardware stores. NAPA and O'Reilly's also don't have anything even close. The dealer/ parts stores online don't either. The interior ones I can probably make work with something from the hardware store. However, the doors to the blower housing use a different style of foam that isn't as porous, so as not to allow for water accumulation/mold growth. Any ideas? Thanks in advance.

Good question - mine was leaking when I bought the car and I just ended up using all purpose gasket maker.
The trick was to squirt the gasket maker into a plastic bag, and then cut off a small corner of the bag so that it could be squirted into the small channel of the lid.
Might help you if there is no alternative.
EDIT: Thought this was about the evap valve box, nevermind. Same thing may still apply if the design is the same.1991 318is Brillantrot daily driver (slow restoration) -
Excellent idea c0rbin9. I will have to remember that tip for future projects. The foam in question is about 1/16" thick by 1/2" wide strips. Has anyone dared take on this tedious task before?Last edited by red318is; 03-29-2017, 08:38 PM.Comment

I redid all those when I swapped both our dashboards and I don't think I put anything on the blend door. Used standard household weatherstripping for the recirculating doors so don't see why you can't use it on the blend, especially since it only needs to seal on full open or full close and even then I'm not sure it manages 100% of the hvac airSeat Shocks....I have passed the baton to John Christy from Ninestitch.

what thickness did you use? Mine is so crumbled it's difficult to tell what was originally there. Oh and I will be doing all the flapper doors not just the blend.Last edited by red318is; 03-31-2017, 03:58 PM.Comment

So I found some foam tape that looks identical to what was used on the exterior flapper doors. My landlord who works in HVAC/plumbing gave me a roll of it so that is what I am going to use all around. Helps to know people I guess. Thanks for the help guys! :)Comment

OP, go with neoprene foam. You can get some from Amazon. It will outlast the car.

So for anyone else looking to do this, I found this build thread
fresh_TD, the foam I was given isn't the same material as factory. It's a closed cell, with a skin, but the thickness, compressibility, and color is the same. It is made from neoprene, though.Comment
