This is like a gift from the Graff Gods! I tested it on so many cans n it lives up to its name.Also this cap doesnt clog up as fast as most outline caps.ive even caught some nice flares with this cap.
Think about how nice a German Outline #1 cap is. Then think about that cap working damn near perfectly on any female-valve can you could possibly use it on. That's basically what this cap is.
