1275 clutch fluid line

Hi All,
Looks like the hydraulic fluid is leaking out at the junction of the line
and the master cylinder.  The metal clutch line screws into an adapter nut
and this nut screws onto the master cylinder.
I've taken everything apart and cleaned it up as best I could and put teflon
tape on the threads but it's still leaking.
What would be the best fix here.
Neither Moss Motors nor VB sell replacement clutch line. so I'm not sure
what to do.
Many thanks as always for any advice.

Adrian
