The Warthog 1-1/2" liquid-filled pressure gauge (PIC 203L series) is a compact, panel-ready instrument built for compressed-air, hydraulic, and fluid-power equipment exposed to vibration and pressure pulsation. The glycerine fill dampens needle flutter for a steady, easy-to-read indication and extends service life in demanding conditions, while the U-clamp bracket makes for fast center-back panel mounting.
Which range should you choose?
This model is offered as positive-pressure ranges plus one vacuum gauge:
- Pressure (e.g. 0–100 PSI): Positive pressure only — what almost every air-compressor and shop-air job needs. Pick a range where your normal working pressure sits around the middle of the dial.
- Vacuum only (0 to 30 inHg): Suction / negative pressure only.
What does "inHg" mean? It stands for inches of mercury — the standard unit gauges use to measure vacuum, meaning pressure below normal atmospheric pressure (in other words, suction). 0 inHg is ordinary atmospheric pressure, and about 30 inHg is a near-complete vacuum — roughly 14.7 PSI of suction. So a gauge marked "30 inHg" reads the entire vacuum range, from no suction down to full vacuum. (By comparison, PSI measures pressure above atmospheric.)
Key specifications

Typical applications
Air compressors and receiver tanks, pneumatic control panels, hydraulic power units, pumps, filtration and process skids, and any application where vibration would shorten the life of a dry gauge.
Available in 13 pressure ranges from a 30 inHg vacuum gauge up to 0-5000 PSI, the Warthog 1-1/2" liquid-filled panel-mount gauge delivers reliable, vibration-resistant pressure indication with a corrosion-resistant stainless steel case and 1/8" NPT center-back connection.
