The Ametek 356013 Open Front Stainless Steel Stem-Mounted 4 in. Pressure Gauge, 1/4 - 18 NPT, 0 - 300 psi is suitable for corrosive environments in chemical, petro-chemical, refining, power, marine, and food and pharmaceutical processing applications. Liquid filled pressure gauges provide users with a number of advantages in certain measurement 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. Liquid filling also provides greater protection of the gauge internals from corrosive atmospheres.

The 356013 can be used with a variety of fill fluids including glycerin, mineral oil, and silicone oil. This 4 in. gauge features a low mount 1/4 in. NPT connection. This model is made with seamless 316L SST Bourdon tubes, which reduces concerns about tube fatigue and stress corrosion cracking.
