can the weatherseal go between the bottom of the air conditioner and the window sill?)

If there is space then yes. It’s a foam so you can manipulate it into the smallest crevices.

does it absorb moisture?

Never had to experience moisture

What is the maximum temperature rating of this foam?

Sorry, no idea. I use it for insulation. It does not come with temperature ratings listed, but as it's very light, thick sponge rubber I wouldn't think it would withstand very high heat.

It can be hand-washed in mild soapy water' rinsed and air-dried as long as the foam has not gotten crumbly with age.
