I have an obsolete tall Kohler faucet in the kitchen, and the aerator is shot. The threads in the faucet appear to be 3/4 female, while the threads on aftermarket replacement aerators are 15/16 male combined with 55/64 female. Any ideas about adapters from one to the other. It looks like I would need a 3/4 male to 15/16 female, or a 3/4 male to 55/64 male.
