The DuraChoice PB254B-400 oil filled pressure gauge has a 2-1/2" dial size, with 1/4" NPT center back mount fitting. It has a stainless steel housing, with brass fittings and a polycarbonate window. Measures 0-400 PSI. Useful for media such as water, oil, gas, or diesel. Dual scale indicates PSI/Bar. The stainless steel case withstands the more demanding conditions found in industrial locations. The liquid filling lessens vibration, lubricates the movement, and keeps condensation from forming.
