These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings. The liquid in the dial reduces needle flutter for precise readings in high-vibration applications. Use them in pumps, filters, regulators, and in process lines to measure and display pressure. Mount gauges with the dial face upright.

Gauges with an internal seal resist clogging and corrosion.

Bottom Connection (Flange Mount)

Lower Back Connection (Flange Mount)

Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer and allow for precise readings in high-vibration applications. Use them with pumps, filters, regulators, and in process lines to measure and display pressure. Gauges meet MIL-G-18997 for resistance to salt spray and washdown environments. They have a safety case that blows out in the back under excess pressure, protecting the operator in front. Mount them with the dial face upright.

The case material and connection threads are stainless steel for protection in corrosive environments, plus the dial is glycerin-filled to reduce needle flutter in high-vibration applications. Gauges are commonly used with pumps, filters, regulators, and in process lines to measure and display pressure.

Gauges with calibration certificate must be mounted with the dial face upright.

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.
