Mine came with a foam gasket to keep the SS off the aluminum and provide a seal. The foam gasket has adhesive on one side and A/S told me the adhesive sticks the gasket to the SS not on the aluminum. Kinda counter-intuitive as there is adhesive on the overlapping part of the gasket that faces out.
There is also a 2nd gasket that goes inside the cover to 'seal' the outlet. It took a long time for that gasket to form and make a decent seal over the outlet.
