80080 Midland Liquid-Filled Pressure Gauge, 30 inHg vacuum range, 2-1/2 in, Lower Mount

The 80080 is the -30 to 0 PSI vacuum option in Midland's liquid-filled gauge family, pairing a 2-1/2 in dial with a 1/4 in NPT lower connection. The -30 to 0 PSI scale makes this a vacuum gauge rather than a conventional positive-pressure model, while retaining Midland's liquid-filled construction.

This SKU is different from the positive-pressure gauges around it: Midland identifies it as a vacuum-sealed liquid-filled gauge with a -30 to 0 PSI range. A 2-1/2 in dial keeps the gauge compact enough for machinery while offering more viewing area than Midland's 1-1/2 in models.

For the physical build, Midland uses a stainless steel case with copper-alloy wetted components and a polycarbonate window; the series is rated from -104°F to 158°F.

Glycerin inside the case dampens vibration and pressure pulsation, which helps keep the pointer more stable and supports the gauge movement over time. Before ordering, match the pressure range and connection orientation to the system, then use the specifications below to verify the remaining dimensions and materials.
