Upgrade your Mopar brake system with this brass SAE brake line adapter from Force 10 Brakes. Specifically designed for Mopar applications, this fitting adapts a 3/16" female inverted flare (3/8-24) to a 1/4" male inverted flare (9/16-20)—a common requirement in Mopar brake conversions or replacements.

Great eBayer! A+++. Will do business again. I used this kit on my 1965 Fairlane and it's a straight bolt-on. Easy kit with all the pieces included. Even worked with the stock 14" x 6" wheels. Makes for an awesome upgrade!

3/16" Brake Line 18" Nickel- Copper, 7/16-24 Stainless Tube Nuts inverted FlareWow, this brake tube is a high quality part! It is copper-nickel, which is easier to bend than a steel tube. It is the same length as the old brake tube. When I replaced the rear, driver side brakes, the closest match I could find was a 12 inch, steel tube from O'Reilly. It was too long and I could not use the clip that holds the tube in place. . . . This one is for the passenger side, rear brakes, and it really helps to have the proper part! . . . Thank you much and Happy Spring, Anthony!
