Does anyone know where to obtain the seal that is basically taped to the air boxes that seal the heater core and A/C boxes to the firewall? I've been googling for quite some time and everything I have found is very porous foam tape whereas the factory seal is more like a rubberized dense foam.

Thanks in advance for any suggestions.

 

I couldn't find anything a few years ago when I had to replace the evaporator core housing. I ended up using some 3M strip caulk. Works pretty good.

 

 

You can find foam and butyl tape at the hvac supply house.......imagine that, sealing up the hvac box with hvac parts lol!

 

Sadly, I never thought of googling for hvac foam rubber gasketing tape. I think that may actually be the way that I try first.

Thanks for the suggestions everyone.
