Our all stainless steel 2 1/2" liquid filled pressure gauges are some of the highest quality gauges on the market. Featuring a 1/4" NPT stainless steel lower mount connection, bourdon tube and movement, they are even more resistant to corrosion than their brass connection counterparts. The gauges are cased in stainless steel and filled with glycerin oil to help correct the effects of vibration and pulsation.


Pressure ranges available from vacuum to 15000 PSI. Good for use with water, oil, gas (WOG) and diesel. IP66 Rating
