Yup I did the same thing except for I didn't soak it in hot water. All I did was take a utility knife and cut 3 small slits in the down part in the middle and was able to stretch it over. Unfortunately I don't think I will be able to get it off without ruining that gasket so it just stays on there permanately. I just take the bottom part off when i wash it. I'm not bothered by it on there because the diffusers from hookah-shisha.com have a small one with it too and that's the one I use for my other hookahs because it fits them all.
