Where the heck do I find this supply line??

[rgouette]

Gotta pinhole leak in a basin supply line..
Thought it would be an easy swap for a replacement..
What I bought was: 9/16-24UNEF Female x M10x1.0 Male
The threads are clearly not mating well...
Just went to the hardware store, & the fella said "must me metric on one side.."
I'm not 100% if this is American standard or not... Can;t find anything stamped...maybe I'm not looking closely enough.
In the below pics, I show the original threaded onto the "T", and the supposed replacement beside it.


Does anyone recognise the supply line with the plastic sheathing...?
Help!

Cheers,
Rich

There is a white tag that says Kohler on it on the cold side

Kohler will send you new parts. I think the branch of the tee is straight thread the run are compression.
