80066 Midland Liquid-Filled Pressure Gauge, 0–200 PSI, 2-1/2 in, Lower Mount

Midland part 80066 is a liquid-filled pressure gauge sized at 2-1/2 in and calibrated for 0 to 200 PSI, with a 1/4 in NPT lower mount. A 200 PSI lower-mount scale makes this model a practical fit for moderate-pressure equipment where a bottom connection works best.

Glycerin filling supports reliable indication where vibration is present, damping pointer activity and lubricating the internal mechanism at the same time. The selected scale keeps the usable portion of the dial focused on moderate system pressures, which can simplify day-to-day monitoring.

Its 2-1/2 in format is a versatile middle size in Midland's liquid-filled lineup, suited to many equipment layouts. 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.

For replacement or new installation work, verify the range and mounting position first, then confirm the connection and construction in the specifications below.
