21b Residule Valve 3/8-24M X 1/8 Fem

This 2Lb Residual Valve eliminates excess pedal travel. The all billet design keeps your brake pads close to your rotors so your driver doesn’t have to pump the pedal. The #3 male end will thread right into your master cylinder and the female end is 1/8 NPT, so you can easily plumb your brake system like you want. Anodized black and comes with a brass crush washer.
