Pasco test gauges for pressure testing water, air and drain systems. The collection includes air test gauges in 30, 100 and 300 psi ranges, a lazy hand 300 psi gauge that records peak pressure, water test gauges with 160 and 300 psi scales, an air test gauge body with valve, and a boiler gauge.
Pick a gauge range where the test pressure falls in the middle of the scale for readability. A lazy hand gauge shows if pressure rose above test level. Check the connection thread, and follow local code for the test medium, pressure and duration required for inspection.
