Industrial Workhorse Four Inch Dial Liquid Filled Gauge With Brass Wetted Parts And Stainless Steel Case Dual Scale From Thirty In Hg To Three Hundred Psi Readouts In KPa And Bar 1.5 Percent Accuracy One Quarter Inch NPT Bottom Mount Pressure And Vacuum

Four-Inch Liquid-Filled Dial Gauge with Brass Wetted Parts
✔️ 4 in dial, glycerin-filled, stainless case, dual scale, bottom NPT

This industrial pressure gauge uses a glycerin-filled dial inside a corrosion-resistant stainless steel 304 case, with brass wetted parts for non-corrosive liquids and gases. It supports single or dual scales (psi, kPa, bar, Hg) and offers 1/8", 1/4", or 1/2" NPT connections. Ideal for pumps, compressors, hydraulic presses, and other heavy equipment in harsh environments.

✅ Brass wetted parts for non-corrosive liquids and gases
✅ Glycerin-filled dial dampens vibration; stainless steel 304 case for IP65 protection
✅ Dual-scale options: psi/kPa, psi/bar, Hg vacuum/kPa, or Hg vacuum/bar
✅ Dial sizes available: 40 mm (1.5 in), 50 mm (2 in), 63 mm (2.5 in), 100 mm (4 in)
✅ Bottom or center-back mounting with 1/8", 1/4", or 1/2" NPT, restricted orifice
✅ Accuracy: ±1.5% FS on 2.5" and 4" dials; ±2.5% FS on 1.5" and 2" dials; operating temp -20 to 65 C

💡 What is an industrial pressure gauge used for in heavy machinery and processing lines?

- In simple terms, it shows the pressure inside vessels and pipes to help control processes and protect equipment. - Handy for monitoring pumps, compressors, hydraulic presses, and pneumatic systems in factories. - Helps prevent dangerous overpressure, detect leaks, and plan maintenance. - It supports readings in psi, kPa, bar, and Hg for flexible setups.
