Widespread Faucet Leak at TEE

[Merry Widow]

Have a Kohler Devonshire faucet that needed 2 new supply lines. I also replaced the TEE that connects to the faucet stem. When I placed the new TEE on, I did not tighten it enough. I was afraid that I would compress the washer too much. When I turn on the faucets, I see no leaks. But, when I touch the Tee, I can tell it is leaking ever so slightly. Is there a way to tighten the tee after the supply lines are on? I have heard that the supply line compression fittings cannot be removed and then reattached.
I have attached a picture of the sink TEE. Thanks

If you just installed the supply line, yes you can remove and replace. I don't suggest doing that if they've been installed for a while.
They do take a set over time.

Or maybe just twist a bit to snug up the tee without removing the supplies. You might have room to do that.

Thank you Terry. No room to turn the TEE but I will give removing and reattaching the supply lines a try. Love this forum.!!

Success>>>>Removed supply lines; tightened the TEE and then reattached the lines. No drips at all. Saved a $200 service call. Thank you again, Terry.
