Help me pick the right sized faucet adapter for my kitchen sink.
Forgive me if the terminology is incorrect, but what I'm looking for is a piece of some sort that I can use to attach a garden hose to my kitchen sink. From what I've gathered, this is called a faucet adapter.
I don't know what size to get, or how to properly determine this. The engravings on the outside of the adapter (I think that's what it is) say: A112.18.1M 2.5 GPM 9.5 L/min.
Some random websites I used told me to take a dime and use it to try to get the right size of the adapter. I've attached pictures of that. The dime slipped right into the adapter, and a nickel is too big to fit in the adapter.
The aerator fits around the spout, thus making it female (I think???).
Any advice anyone could provide would be super helpful, and if you need more info from me, please please ask away.
