Need kitchen sinc pipe fitting.?

The old hose that connected to the supply, take that to Ace Hardware and show it to the man in the plumbing aisle. He'll be able to set you up.

You're showing us what appears to be a 3/8 female compression thread fitting, but then you mention a 3/8 pipe. I know you didn't mean to but you just confused some terms - there's such a thing as 3/8" pipe threads, which are RADICALLY different from 3/8" compression. Just take your old connection that worked to the store and match threads and you should be good to go.

Whenever I change out a faucet I get a flexible faucet supply - the end that connects to the faucet is almost invariably 5/8" female threads, industry standard in the US - and the supply side is usually 3/8" female compression. I get flexible supplies that are a couple of inches longer than necessary to provide plenty of leeway while working. They'll usually be hidden by the cabinet when you're done anyway so unless you have a pedestal or wall-mount sink, being super-precise with lengths isn't a big deal.

Good luck with it.

[edit]

Guys, I would swear it's 5/8" compression threads on the faucet, but to be honest I'm not sure. I don't have any supplies on hand to look at. I don't even look at the threads anymore, I just look to see that the supply hose says "faucet" on it and go on from there. If you tell me it's 1/2" MIP I won't argue.

The vast majority of the supply connections coming out of the wall, however, have all been 3/8" compression. That much I'm sure about, to the tune that it's a weird day that rattles my rhythm when I have to go back and find a different supply for a different size, or an adapter.

Kitchen Sinc

So you have 3/8 male pipe as the source? Get 3/8 FIP to 1/2 MIP adapter. Then get the right length hose with 1/2" FIP ends.

Here is a pic of the old hose fitting. The tag is also in the photo.
