4" Oil Filled Pressure Gauge - Stainless Steel Case, Brass, 1/4" NPT, Center Back Mount Connection

This 4" center back mount liquid filled gauge is great for large projects. The dial is legible from a distance and the stainless steel case is made for duty in harsh environments. The gauge has a 1/4" NPT brass connection as well as a brass bourdon tube and movement.

Liquid-filled pressure gauges resist vibration and pulsation better than dry gauges. Gauges are available in ranges from Vacuum to 0-15,000 PSI and can measure a variety of media, including water, oil, gas (WOG) or diesel.
