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.
