600 Series 4-Valve Manifolds 4-Valve Efficiency ?C Vacuum, low side, high side, and refrigerant lines are individually connected and controlled. No need to switch charging lines. 4 Times Faster Evacuation ?C 3/8" vacuum port and oversize internal passages evacuate systems four times faster than ordinary manifolds. 3/8" port has greater area than combined inlets of high and low side lines. Deep Vacuum Valve Design ?C Proven diaphragm-type, soft-seat valves require only fingertip pressure to close completely. One turn to full open/close. Superior for deep vacuum service. Precision Gauges & Protective Boots ?C Unique design with easy to read color-coded scales provides superior resistance to shock, vibration and pulsation for superior performance and extended gauge life. PolarShield Hi-Performance Hoses ?C 800 PSI working pressure, 4,000 PSI burst pressure (not all models include hose). Ergonomic Handles ?C Durable, soft-touch non-slip surface, even with oily fingers.
