Wilwood 4 psi Gold Residual Valve Kit with Female Inverted-Flare Adapters

The four-psi valve and supplied adapter pair provide a residual-pressure connection for an appropriately specified high-vibration brake circuit. Each adapter converts a native pipe port to a 3/8-24 female inverted-flare seat for three-sixteenths-inch hard line. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and builds disc brake systems, with calipers, master cylinders, rotors, brake lines, fittings and valves serving street-performance, motorsport and specialized applications. Selecting an individual part requires checking how it works with the rest of the braking assembly.
