For brake line repair or fabrication work, it gives you a female threaded connection on both sides so you can join two male threaded tube ends inline and make one continuous run.

Will this here fitting work with standard brake lines, or is it some kinda special size?

This female tube joiner uses the 9/16 inch, 18 NF thread specification, so it's made to work with standard brake line fittings you'd find on most cars and light trucks.
