Liquid-Filled Pressure Gauges

80463 Pneumatic Pressure Gauge, 4-in Dial, 0 to 100 psi Measuring Range, +/-1.5 % Accuracy

Liquid-filled pressure gauges are designed for applications where vibration, pulsation, and changing pressure conditions can make a standard dry gauge harder to read. The liquid inside the gauge helps dampen pointer movement and protects the internal mechanism, making these gauges a strong choice for demanding industrial equipment and pressure-monitoring applications.

Our selection of liquid-filled pressure gauges includes multiple pressure ranges, dial sizes, connection sizes, and mounting configurations. Many of these models use a glycerin fill, making them suitable for environments where equipment vibration or pressure fluctuations can affect gauge readability.

When choosing a liquid-filled pressure gauge, start with the pressure range required for the application, then confirm the dial size, mounting position, connection size, and connection type. Lower-mount and back-mount configurations are available for different installation requirements, and individual product pages include detailed specifications to make comparison easier.

Liquid-filled gauges are commonly selected when a more stable reading is needed than a standard dry gauge can provide. They are used across industrial equipment, pneumatic systems, machinery, test equipment, and other pressure-monitoring applications where durability and readability are important.

Use the products below to compare available liquid-filled pressure gauges by pressure range, dial size, mounting style, connection size, and construction. For additional styles and configurations, shop all pressure gauges, or browse back-mount pressure gauges for rear-connection installations.
