If you are going to stick with analog gauges, stick with the best. Imperial 600 series vacuum rated manifold gauges feature four valves which means that vacuum, low side, high side and refrigerant, are individually connected and controlled for productivity, with no need to switch charging lines. A 3/8vacuum port evacuates four times faster than ordinary manifolds. Soft-seat valves require only fingertip pressure to completely close. Full open to close is one full turn. Precision gauges have easy to read color scales and provide superior resistance to shock, vibration, and pulsation. Models that include hose feature Imperials Polarshield Hi-Performance hose - UL® approved, 800 PSI working pressure, 4,000 PSI burst pressure.
