Installing new faucet in kitchen sink, issue with supply lines
Hey guys
I'm sure this is a super easy question, but I'm getting ready to head out to the home improvement store and want to make sure I only have to go once more for the day.

I'm installing a new faucet for my kitchen sink, and the supply lines included with the faucet are not only too short, but they are the incorrect size to fit on my shut off valve. The shut off valve is 1/2, and my connection on the supply line is 3/8. Can anyone tell me what I need to extend this line to not only reach the water supply, but also fit it? I'm horrible with plumbing terms like FIP IPS etc etc, so spelling it out for me is essential. Haha
Thanks everyone!!!!

I was hoping you would respond! No, let me show you what the old set up looked like.

That is a 1/2" connected to the valve, whereas the new faucet has 3/8 compression fittings on the supply lines

I got side tracked with the kids here...
I am not sure you will find what you need at the home store.
What I believe you can do is get a brass 1/2 x 3/8 adapter for the valve end. Then you will need a 3/8 x 3/8 braided extension and connect to the supply with a coupling.
Possible they make a supply with a male end....

And this here. You need to make sure there is a rubber washer in the 1/2" side and it has the fine thread pattern that your old valve has.
Your old valve was a 1/2" compression originally I believe. Dont know how they got that supply threaded on there???? The thread pattern is different. I would need to se the threads on the valve with the supply removed.

Every HD in my area is sold out on those. I guess I'll head there and ask if they've got anything similar but under a different SKU. Until then I'm going to look on lowes and see if they've got anything.
So your saying that my current setup isn't correct? How does that compression adapter work? Does it thread on, or does it slip over the threads?
Ha, I thought this was going to be a pretty easy install...
Thanks again lawrosa!

Yes that will work. But it needs a washer on the inside. It threads onto the old valve. No washer then it will leak. Must be same thread pattern. Cant use teflon tape on that.
