80331 Midland Dry Pressure Gauge, 0–15 PSI, 2-1/2 in, Center Back Mount

Midland part 80331 combines a 0–15 PSI pressure scale with a 2-1/2 in face and a center back connection layout.

As a dry pressure gauge, this model is intended for installations where a liquid-filled movement is not required. Gauge type should be confirmed along with pressure range and mounting position. The 0 to 15 PSI scale is aimed at low-pressure monitoring, where a higher-range gauge would spread the useful reading over a smaller portion of the dial.

The rear 1/4 in connection keeps the pressure port behind the gauge face; match that center-back layout to the existing equipment.

The 2-1/2-inch face provides the largest viewing area among these standard dry-gauge sizes. Construction for the series includes a steel case, brass connection components, and a plastic lens. Match all four primary selection points—range, dial size, connection size, and mounting style—to the equipment rather than relying on appearance alone.
