The Mityvacs Fluid Evacuator Brake Bleeding Accessory Kit is design for use with Mityvac Fluid Evacuators, P/Ns 7200, 7201, 7300 and 7400. It is provided standard with P/N 7300, but must be ordered separately for the other evacuators. The joining of these two Mityvac(r) products produces a quick and easy method for one-person vacuum bleeding of hydraulic brake systems. This Kit includes a durable brass flow control valve and universal brake bleeding adapters that will fit most bleeder screws.
