    About Pressure Gauges
    industrial info icon

    Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

    Steam Pressure Gauges

    Designed for use with boilers, these gauges have a dual scale that displays pressure in psi and feet of H₂O and displays temperature in °F/°C.

    and Brass With

    Ball-Valve-Style Drain

    Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.
    316 Stainless Steel—316 stainless steel indicators are more corrosion resistant than brass or bronze indicators. They have a stainless steel drain valve and be used on expansion tanks.
    Needle Stem—Indicators with needle stem have a stem in the lower shut-off valve to clear the orifice as the valve closes.
    Automatic Shutoff—Indicators with automatic shut-off will temporarily close if the gauge glass breaks. The valves must be closed manually for permanent shut-off.

    Low-Pressure Differential Gauges with U-Tube

    Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.
