Most of the time rodents will not go through expanding foam sealant, most of the time. If you use some steel wool and then inject the foam into steel wool that would keep even the adventurous rodents out. How much heat? Expanding foam should have a heat rating. If you are worried about just hot pipes you can get a little piece of pipe insulation and put that around the pipes first.
Comment on How would you seal this gap around kitchen sink plumbing?
SoySaucePrinterInk@sh.itjust.works 8 months agoThanks, are there any that you’d recommend which are heat and rodent resistant?

Unfortunately, I don’t have any experience with the foam sealants that claim to be rodent resistant. But, they do exist, so that is likely a good place to go.
