A dependable 2.5" dry utility pressure gauge built for panel-mounted air, water, oil, and gas applications. The U-clamp center-back mount makes it a clean fit behind regulators, manifolds, and control panels, while the 1/4" male NPT connection drops straight into most standard ports.
Which range should you choose?
Pick the range type that matches what your system does:
- Pressure (e.g. 0–100 PSI): Positive pressure only — what almost every air-compressor and shop-air job needs.
- Compound (e.g. 30 inHg vacuum to 100 PSI): Reads both vacuum and positive pressure on one dial — for systems that pull suction and also build pressure.
- 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.)

Applications
Suitable for air, water, oil, gas, and most media that are non-corrosive to brass — ideal for compressed-air systems, pneumatic equipment, regulators, and OEM panel builds.
This 2.5-inch chrome-cased dry gauge offers reliable, repeatable readings in a rugged, low-maintenance package. With U-clamp panel mounting and a 1/4" NPT back connection, it's an easy, economical upgrade or replacement for shop and industrial pressure-monitoring needs.
