The cap is lose. I press it down/in.. sits for a while, and get lose again.

How to fix?

Is it bad for the bike?.. Dust and water can get inside.

If you use any kind of superglue or Gorilla Glue, you will never be able to get that grommet back out without risking frame damage. Don't do it. Those grommets are meant to be removable to make it easier to run new cables or hoses. If it's slipping out, you just need something to increase it's diameter a bit so that friction will hold it in place. It's not a submarine or a spaceship. It doesn't need to be an absolutely airtight seal. For a quick and dirty fix, maybe try just cutting a small sliver of electrical tape and wind it around the base of the grommet, then shove it in. You'll have to experiment with just the right amount. A better option would be self-fusing silicone or rubber tape. But you don't want to glue anything to the frame with a permanent adhesive unless you're absolutely sure you'll never need to remove it for the lifetime of the frame. Maybe something rubbery like Shoe Goo or rubber cement would work too. You want something that sticks semi-permanently but can be peeled away without heroic measures (e.g. nasty solvents or drilling it out). I have a carbon frame where one of the grommets is missing entirely. I'm planning to experiment with Sugru which is a sort of tacky silicone putty.
