To help solve sizing problems, this cache faucet adapter set has four cache sizes: standard m24x1, junior m21x1, tiny junior m18.5×1, tom thumb m16.5×1 (sizes in millimeters). Standard size fits faucets that take a Cache aerator corresponding to the size of a quarter. Junior size corresponds to the size of a nickel. Tiny junior corresponds to the size of a penny. Tom thumb corresponds to the size of a dime. Will only work with Cache style faucets that match one of these four sizes. Each adapter converts your cache faucet to take a standard female threaded aerator. This set is your one-stop solution to get four sizes of cache adapter, giving you good odds of getting the size you need. By converting your faucet to a standard aerator, you can connect it to filters and to washing machines (provided they have the same threads and sizing as a standard size female aerator, which is often the case).
