    About Pressure Gauges
    industrial info icon

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

    Vibration-Resistant Pressure Gauges

    A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications. Gauges are commonly used with pumps, filters, regulators, and in process lines to measure and display pressure. Mount them with the dial face upright.

    Panel-Mount Ultra-High-Pressure-Regulating Valves for Air and Inert Gas

    Image of Product. Front orientation. Pressure-Regulating Valves. Panel-Mount Ultra-High-Pressure-Regulating Valves for Air and Inert Gas.
    These valves are rated for inlet pressures up to 6,000 psi. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Threads below the adjustment knob and an included mounting bracket let you install these valves in instrument panels. They have two gauge ports. An internal strainer traps debris.
