I am selling this because it no longer fits my faucet after moving. It is made of stainless steel and was attached to a kitchen faucet. I used it for about 2 years, but it is in good condition. The included 22mm to 24mm conversion adapter is not included. Therefore, the only faucets that can be installed are [Foam faucet with external thread: Diameter 22mm] faucets only. Please be aware.
