About Pressure Gauges

Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

Drinking Water Pressure Gauges

Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water. The dry dial on these gauges is best for low-vibration applications, since the needle can bounce if the gauge is shaken. For more accurate readings under heavy vibration, use a liquid-filled gauge. Mount gauges with the dial face upright.

Vibration-Resistant Drinking Water Pressure Gauges

Clearly read pressure levels in your drinking water system, even with heavy vibration. The dial face is filled with glycerin, which absorbs shock and keeps the needle steady. These gauges meet NSF/ANSI 61 for drinking water. Mount them with the dial face upright.

Pressure-Regulating Valves for Drinking Water


Valves	Valves With Union Fitting

These valves meet NSF/ANSI 61 for use in drinking water systems. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. All valves have a gauge port. An internal strainer traps debris. Body is bronze for durability and a long service life.

Union Fitting—Valves with union fitting disassemble for easy installation and removal.
