Mousseur aérateur invisible pour votre installation, réparation ou rénovation en kitchen

If the thread is on the outside of the outlet spout, you'll need an aerator with the thread on the inside, i.e. female.

To find the aerator for your faucet, you first need to define its size:

- For kitchen faucets, the ring size is mainly 22 x 100 female.

- For lavatory faucets, the ring size is mainly smaller than for kitchen faucets: 19 x 100 female.
