Re: Problem with my small hookah
That's not a grommet. That's just the nipple that the bowl fits down on. It still needs a gasket to make a seal.
Any good vendor should have something that will fit. If push comes to shove, wrap it with electrical tape until the bowl fits down on it snugly.
The same can apply to your base and your hose. At least until you can get some proper replacements.
