520 Series 2-Valve / 4- Or 5-Port Manifolds
• Two Integrated Auxiliary Ports – Provide additional hookups for use with a micron (vacuum) gauge, vacuum pump, adding tracer dye, adding oil, purging non-condensables.
• Deep Vacuum Valve Design – 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 – Unique design with easy to read color-coded scales provides superior resistance to shock, vibration and pulsation for superior performance and extended gauge life.
• Ergonomic Handles – Durable, soft-touch non-slip surface, even with oily fingers.
• PolarShield® Hi-Performance Hoses – 800 PSI working pressure, 4,000 PSI burst pressure (not all models include hose).
• Swivel Hanger
