SQTG4A and SQTG4B Four Gauge Kits include a 30 PSI gauge, a 300 PSI gauge, a 5 PSI gauge, a 35” water column gauge, and a high pressure test block plus six pressure tap valves either type A or type B depending on which kit is specifi ed. The hose quick disconnect allows for attachment of any one of the gauges. A leak check pressure tap valve can be anywhere in the system with the proper gauge attached for leak check testing. This kit also allows the service technician to test all pressure regulators, including the fi rst stage, using the 30 PSI gauge, a 2 PSI regulator using the 5 PSI gauge, and low pressure 11’ W.C. regulators or appliance manifold pressure using the 35” WC gauge.
