Wilwood Residual Pressure Valves, Disc/Drum, 2 & 10 psi

Residual pressure valves retain a minimum brake line pressure to help eliminate excessive pedal travel. These residual pressure valves are 2 PSI and 10 PSI for drum brake systems to compensate for return spring tension and maintain wheel cylinder sealing in the drums. This residual pressure valve is billet aluminum and red anodized for easy identification. 2 PSI & 10 PSI. 1/8-27 NPT Inlet/Outlet. Blue/Red anodized. Aluminum. 1/8" NPT port at each end. Use 2 PSI for disc brake and 10 PSI residual valves for drum brake applications only.  Inverted flare or AN threaded adapter fittings to the 1/8" NPT female thread will be required and are noted below and available.
