80067 Midland Liquid-Filled Pressure Gauge, 0–300 PSI, 2-1/2 in, Lower Mount

When the application calls for a 0 to 300 PSI gauge, the 80067 provides a glycerin-filled Midland design with a 2-1/2 in face and a 1/4 in NPT lower connection. Its scale covers a practical mid-range pressure band without forcing the user to read a much broader high-pressure dial.

The 300 PSI lower-mount version gives buyers a midpoint between 200 and 400 PSI models in the same 2-1/2 in family. The 2-1/2 in face provides a practical balance between dial visibility and overall gauge size for general equipment use.

Midland specifies a stainless steel case, copper-alloy wetted parts, and a polycarbonate window, along with ±1.5% of span accuracy and a -104°F to 158°F temperature range.

Its glycerin fill helps calm pointer movement caused by vibration and pulsation, while also lubricating the internal movement for longer service life. The key selection points for this SKU are its pressure span, dial diameter, and mount location; the full specification table below provides the remaining details.
