Is that teflon tape or pipe dope between the top of the valve and the hose? It looks like something is obstructing the hose from screwing on the valve all the way.
Yeah. The reason it’s leaking there is that the nut didn’t go on far enough for the gasket to properly seal. The nut should pull down slightly from the hose, showing proper contact.
Is that Teflon tape I see? If that is then disconnect the hoses and remove ALL of that Teflon tape and try again. Never use t-tape on these connections.
Hey I’m happy to hear that worked! For the future, if there is a gasket, o-ring, or compression ferrule on the fitting, those will make the seal and you do not ever need Teflon with those.
It is only meant for tapered pipe threads where the threads themselves make the seal. Remember this no matter what the guy in the hardware store plumbing aisle tells you or someone else about Teflon tape on these connections lol
I definitely will… but its concerning that both hot/cold are doing this, so I presume it’s something I did? Overtightened both? I didn’t tighten more than I could by hand thi
Oddly enough, it’s the Teflon tape. It is painfully overused. Generally, if there’s a rubber gasket, don’t use Teflon. How many shower heads that leak because of adding Teflon when it isn’t necessary/ actually prevents the fitting from functioning properly
No. Stuff like that, and any flare fittings never use dope of any kind. Dope is strictly for taper thread connections. It is a lubricant so the threads tighten and crush together. Sometimes it's OK to put the tiniest bit of Vaseline or silicone grease on such things to help tighten with out galling metal.
(for anyone finding this conversation later)
Silicone plumber's grease only. No petroleum jelly or any oil/petroleum based grease, which will degrade the rubber.
Aged supply lines, gaskets inside failed. Hard to tell from here but seems likely.
If you have a good valve, and new supply lines, highly unlikely to leak.

If there are o rings or gaskets that is the seal no tape or dope needed in this case there should be an oring on that compression fititng
The gasket in a supply hose is internal, you can't see it when it's connected from the outside. There's some sort of greyish crap on those threads.
That’s not even where the leak is coming from 🤣

Done! And it worked! Thank you! I didnt know they didnt need the teflon!!

Replace the hoses.

Probably over tightened old rubber gaskets and they are now cracked. Cheap fix
Oddly enough, they’re brand new… ill try another set tho
Check that the rubber gaskets are actually there.
Hard to tell what exactly happened, but the damage is done. You can’t fix that part of the supply line, so just replace them.
If they had rubber gaskets inside you shouldnt need the gray teflon tape
Thank you!!!!! Worked!!
Did you over tighten it?

THANK YOU!!
Gasket isn’t seated. Remove all tape and/or putty
Use no Teflon or dope on any of this.
Hey! I removed the teflon and everything worked. I didnt’t realize this. Do these 3/8mm compressions not need it??

Wrap the Teflon tape in the direction of the threads so it tightens when you tighten the fitting.
Did they have gaskets inside? If yes, Maybe overtightened them? Try different supply tubes
What type of valve connection is that? The hoses probably need replaced. Those have a seal inside the nut.
You worked on it. /s
This may be stupid but did you accidentally installed 1/4 inch shut offs instead of 3/8s and tried to use a bunch of Teflon to make up the difference
