Identify leaking braided supply line

[Viz]

Hi all,

I have a braided supply line that is leak and I can't figure out who makes it. All I can see on the ferrule is that it appears to be stamped with A B . The nut on the line looks like the one in the picture with that pattern in it.

Thanks for any help!

Supply lines are usually pretty interchangeable. The reason to know the brand of yours might be to let you avoid that brand.
