Pressure Gauges
These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.
Gauges with 304 stainless steel case or ABS plastic case have better corrosion resistance than gauges with brass or steel case.

- For Use With: Air, Water, Hydraulic Fluid, Carbon Dioxide, and Natural Gas
- Accuracy: ±2% Mid Scale (Grade B)
- Mount with the dial face upright

Miniature Pressure Gauges
The small dial on these gauges allows for installation in tight spaces. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.
Gauges with ABS plastic case are more corrosion resistant than brass-case gauges.
