Got an old brake line fitting that's shot and need to know if this'll swap right in, it's the female 3/8X24NF thread, and I see it's got a key slot. That what I'm looking for?

The key slot is built into this fitting specifically to lock it in place and keep it from rotating during installation or under pressure. For brake line work where the female 3/8X24NF thread is the spec, this one fits that application. The key slot is part of what makes the connection hold secure rather than backing out or shifting over time, which matters a lot in brake systems where you can't have any slop in the line.

Will this fitting work on standard 3/8" brake lines?

This Brakequip fitting is made with a female 3/8X24NF connection, which should provide a secure fit for compatible brake line applications.
