Glycerin pressure gauge ø39 "OPG"

Easily set the pressure range and value!

We issue various certificates for pressure gauges (traceability diagram, conformance certificate, inspection results, configuration certificate). For details, please contact us.



  • Stainless steel case <improved contact durability>
  • Sealing of pure glycerin liquid <improved pulsation effect>
  • Safety mark provided as the standard
  • 270-degree pressure angle indications for improved clarity.
  • This gauge can be mounted directly onto the pressure port of the modular type hydraulic circuit.
  • he pressure gauge root section is equipped with special slots for absorbing pulsating pressure and surge pressure.
  • Even of modular valves are stacked, pressure gauges do not make contact with each other.
  • Movement of the pointer due to mechanical vibration is absorbed by the viscous drag by pure glycerin liquid in the hermetically-sealed pressure gauge. Movement of the Bourdon tube is also absorbed, improving the absorption effect of the pulsating pressure of the fluid.
  • The pure glycerin liquid serves as lubricating oil for the friction part of the bearing and gear in the pressure gauge, thereby further improving the durability of the internal mechanism in comparison with the existing products.
  • Safety measures are provided to ensure that the transparent sheet at the front is not shattered, and hydraulic oil is purged from the safety valve in the case that the Bourdon tube is broken.
  • The green safety mark attached to the circumference of the transparent sheet assists in the setting of a pressure range and values.
  • Select a pressure gauge whose top pressure reading is more than double the applicable pressure range.
