4"dial 0-25 mpa 3/8 bsp bottom complete ss glycerin filled

Dial Size4 inches (100 mm)Pressure Range 0 to 25 MPa (0 to 250 bar / ~3625 PSI)Connection Size 3/8" BSP (British Standard Pipe)Connection Location Bottom Mount (Vertical)Case Material Stainless Steel (typically SS 304 or SS 316)Wetted Parts (Internal/Thread)Stainless Steel (typically SS 316)Liquid Filling Glycerin (99.5% pure)Accuracy Class±1.0% or ±1.6% of full scale deflection Window Material Safety Glass or Poly carbonate Dampening Mechanism: The glycerin filling protects the internal components by dampening severe line pulsations, vibrations, and pressure spikes. It also lubricates the gear movement to extend service life.Full Stainless Steel Construction: Both the housing case and the internal wetted parts (bourdon tube and socket) are made of stainless steel. This makes the gauge highly resistant to corrosive environments and suitable for harsh chemical, oil, and gas applications.Safety Features: Typically includes a blow-out device/rubber plug at the top or back of the case to relieve internal pressure build-up safely.Temperature Limits:Ambient: -20°C to +60°C (-4°F to 140°F)Medium/Process: Maximum +100°C (212°F) Note: High process temperatures may discolor the glycerin filling over time.
