Product details
This Wilwood tube nut is sized for 3/16-inch brake tubing and a 1/2-20 master cylinder port. It bears on the formed tube flare to retain the hydraulic connection; it is not a hose-end adapter. Since its founding by Bill Wood in 1977, Wilwood Engineering has developed a range serving motorsport, street-performance and specialized brake applications. Based in Camarillo, California, it designs and manufactures disc brake systems, calipers, brake rotors, master cylinders, valves, fittings and brake lines. Each component should be selected for compatibility with the complete braking system.
Technical Details

- Connection specification: 1/2-20 inverted flare for 3/16

Fitment & Compatibility
Check the master cylinder's port thread, tube size and inverted-flare seat before forming the line. Wilwood's product note identifies a tandem cylinder application, but the nut should be selected by the actual port rather than vehicle make alone.
