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.
- For Use With: Water
- Accuracy: ±2% Mid Scale (Grade B)

Thread these fittings onto your testing equipment by hand for a secure connection in testing applications—no tools, tape, or sealant required. Use them with gauges and other equipment as a temporary connection. When pressure is applied, the O-ring on the outlet presses against the testing equipment, creating a tight seal.
Adapters with intermittent swivel rotate 360° until tightened for easy installation.

Pressure-Regulating Inline Hydraulic Valves

When input pressure varies, use these valves to maintain a consistent pressure. They are often placed after a directional-control valve and before an actuator, such as a cylinder. They have an indicator/gauge port for the inlet and one for the outlet so you can monitor that output pressure remains steady.
