Open Front Stainless Steel Gauges – 4″ Model 656

The 656 Series are suitable for corrosive environments in chemical, petrochemical, refining, power, marine, and food and pharmaceutical processing applications.They are ideally suited for uses on equipment where excessive vibration and pulsation are encountered, such as pumps, compressors, machine tools, etc. The liquid fill minimizes the effect of these severe environments, protects the gauge internals, and provides continuous lubrication on the mechanism, all adding up to extended service life.
