I am refurbishing my non-AC heater box and want opinions on what to use on the doors that used to contain rotten foam. Without some sort of seal, the doors will leak.

Please let me know your thoughts.

Re: HVAC Door Foam

How about the foam tape that is used on a pick up bed when they install a cap ?

Re: HVAC Door Foam

If it's what I'm thinking, that's way too thick. The foam he needs is closer to about 3/16" wide and thick... The foam for truck caps is more along the lines of 2-3" wide and probably 1/2" thick.

Yes, it is thin and needs to be compressible. It could cover the entire door, but doesn't have to.

I am hoping there is some sort of product that I can use that doesn't rot and become gooey after 10 years and then blow into the passenger compartment...like the original stuff does.

I cannot be the only one with this imponderable.
