    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.

    Heavy Duty Liquid-Level Indicators

    Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators have steel chambers, glass windows, and seals made of fiber and SBR rubber to resist corrosion and withstand higher temperatures than other level indicators. Use them with a wide variety of liquids, such as petroleum, chemicals, and natural gas. All meet ASME BPVC.VIII.1 safety standards for pressure vessels, so they’re approved for use in low-pressure water and steam applications too. Their gauge is made of reflex glass, which shows the level of liquid behind the glass, but not the liquid’s color or any particulates in it. Also known as armored level gauges.

    Shut-Off Valves—Add shut-off valves to stop flow with the turn of a wheel. They’re offset to help you access the inside of the gauge’s glass with minimal disassembly. This makes it easy to clean or replace the glass or entire indicator. These valves also stop flow automatically if the indicator glass breaks, preventing the loss of fluid. However, for permanent shut-off you must close them manually. Put one valve on top of your indicator and one on the bottom for a 90° connection between the indicator and your tank. To connect the female threads on your indicator to the female gauge threads on the shut-off valve, use a male pipe nipple (not included).

    Glass

    Use this gauge glass with heavy duty level indicators.
    Clear Glass—Clear glass helps you monitor the color of liquid and any particulates in it, in addition to the liquid’s level. Use two pieces of this glass in your indicator; the liquid flows between them, so you see straight through.
    Gaskets—Use gaskets to seal the glass.
