I have a Kohler k-72760-4, and I can't figure out how to remove the aerator. It looks like an inside male threaded aerator and I tried buying a key to unscrew but it looks like I bought one that was too big, and even still I don't see the slots where a smaller key would fit.

What key do I need to remove, and can I remove without a key using a screwdriver or some other tool?

That does not look like the sort of aerator that uses a key to remove.

The only way I know to remove them is grip them snugly either with channel-locks and a washcloth between the plier jaws and the aerator (so as not to mar the finish) or a rubber strap wrench and unscrewing the aerator counterclockwise.

  • Which part would I grip? The aerator is inside the faucet so I don't know what I'd be able to get a grip on. Are you saying I should try to slip in between the aerator and the inside faucet wall? Sep 12, 2021 at 10:56
  • Oh I see, the whole housing comes off with enough force if I twist around the outside of the entire tip. Sep 12, 2021 at 11:06
