The DuraChoice PS404L-V00 oil filled vacuum pressure gauge features a 4" dial size, with 1/4" NPT lower mount fitting. It has a stainless steel housing, with stainless steel fittings and a polycarbonate window. Measures -30HG-0 PSI. Made for water, oil, gas, or diesel. Dual scale shows PSI/Bar. The larger dial face makes the gauge easier to read. The oil lessens vibration and keeps the movement lubricated. Using stainless steel is beneficial to avoid corrosion.
