Where to buy replacement HVAC foam?

[SkorcherX]

I need to replace part number 13.



Where does one find this? Also if there is a DIY on perhaps using something that can be bought at Home Depot that would also be much appreciated.

Thanks!

I used home air conditioning foam, the stuff that seals up the crack in the window mounted units, found it at Home Depot in a bag
