Wilwood GS Master Cylinder Inlet Adapter, 7/16-20 Male to -6 JIC, Aluminum

This aluminum inlet adapter presents a -6 male flare at the GS remote master cylinder. The cylinder-side thread is 7/16-20, allowing the appropriate reservoir plumbing to be selected independently of the master cylinder body. For Wilwood Engineering, component selection forms part of matching a complete brake system to its application. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures disc brake systems and a range of calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
