80604 Midland Liquid-Filled Pressure Gauge, 0–100 PSI, 1-1/2 in, Lower Mount

For equipment that needs 0 to 100 PSI indication, the 80604 uses a liquid-filled Midland gauge body, a 1-1/2 in dial, and a lower 1/8 in NPT process connection.

This is the 100 PSI lower-mount option in Midland's compact 1-1/2 in liquid-filled group. That pressure span makes it a logical choice when the system operates at the lower end of the gauge range and small changes need to remain visible. The 1-1/2 in face keeps the gauge compact for equipment layouts where panel and plumbing space are limited.

A stainless steel case protects the gauge body, while copper-alloy wetted parts and a polycarbonate window complete the construction. Accuracy is ±1.5% of span. Glycerin inside the case dampens vibration and pressure pulsation, which helps keep the pointer more stable and supports the gauge movement over time.
