The Mityvac Pump and Dual Converter by popular demand -- The Mityvac SilverlineTM Plus. This kit includes our premiere SilverlineTM Dual Converter Pump, producing vacuum or pressure at the flip of a switch. With its compound gauge, vacuum and pressure can be easily read without having to change tubing or ports. The kit allows you to vacuum bleed virtually any brake system, and with the MityfillTM Automatic Fluid Feeder, the need to monitor the fluid level in the master cylinder while bleeding the system is eliminated. Making brake bleeding truly a one-person operation. In addition, the colored vacuum plugs allow isolation of the vacuum circuit for testing and for identifying circuit components during reassembly. Designed for use with pressure and vacuum actuated devices, the SilverlineTM Plus is an indispensable tool.
