Extreme-Vibration-Resistant Pressure Gauges

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.

Gauge Guards

Also known as isolators or diaphragm seals, these protect gauges from corrosive process media. Fill guards with hydraulic oil (not included) before use.

316 Stainless Steel Body

316 stainless steel guards provide excellent corrosion and chemical resistance and can handle higher temperatures and pressures than plastic guards.

Refrigeration Pressure and Vacuum Gauges


	Bottom Connection

Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement. Also known as compound gauges, these measure both pressure and vacuum.
