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, Ethyl Alcohol, Natural Gas, and Nitrogen
- Accuracy: See table

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 brass case are more impact resistant than ABS plastic-case gauges.
- For Use With: Air, Water, Hydraulic Fluid, and Natural Gas
- Accuracy: ±5% Full Scale (Grade D)

High-Pressure-Regulating Valves for Water, Oil, Air, and Inert Gas

- For Use With: Water, Oil, Air, Inert Gas
- Temperature Range: 32° to 300° F
Withstand more than six times the inlet pressure of standard pressure-regulating valves. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a 303 stainless steel body for corrosion resistance in harsh environments.

Miniature Ultra-High-Pressure-Regulating Valves for Water, Air, and Inert Gas

- For Use With: Water, Air, Argon
- Temperature Range: -15° to 165° F
For extremely high-pressure applications in tight spots, these valves handle the same inlet pressures as other ultra-high-pressure-regulating valves within a smaller footprint. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. All have two gauge ports. Body is nickel-plated aluminum for good corrosion resistance. Valves are no-bleed style, so they keep the process gas contained within the valve.
