4’’ DIAL0-40 MPA 3/8 BSP SS CASING INT BRASS GLY FILLED

Dial Size 4'' (approx. 100 mm)Standard industrial nominal diameter for process visibility.Pressure Range 0–40 MPa Measures high pressure up to 40 Megapascals (~400 bar / ~5,802 psi).Process Connection 3/8'' BSP British Standard Pipe parallel/conical male or female thread mount.Case Material Stainless Steel (SS)Corrosion-resistant outer casing (typically SS304).Wetted Parts Internal Brass Socket and bourdon tube/movement made of copper alloy (brass), suitable for non-corrosive media like air, water, or oil.Filling Glycerin-Filled Dampens pointer flutter from vibration and pulsation, lubricating internal gears.Accuracy Class Typically ±1.0% to ±1.6%Standard full-scale deflection error margin for industrial gauges.Application NotesMedia Compatibility: Internal brass wetted parts mean this gauge cannot be used with corrosive chemicals, strong acids, or oxygen service (which requires oil-free stainless steel wetted parts like SS316).Environment: Glycerin filling prevents condensation fogging and protects internals from high
