SOLFRUNT 1901 Wall or Stem Mount Pressure Gauge

1901 Pressure GaugeThe SOLFRUNT 1901 process gauge is available in 4 ½” or 6” gauge sizes, with an aluminum back-flanged case for applications needing stem or wall mounting. These gauges are available with wetted surface material in brass/phosphor bronze.

The 4½" size is available as a dry or liquid filled pressure gauge from the factory or your local stocking distributors, or can be ordered with a liquid fill kit for filling in the field.

Model 1901 SOLFRUNT process gauges are supplied in many different ranges, including vacuum, compound gauge, and psi gauge pressure ranges from 30" Hg vacuum through 1000 psi. Dials are available in psi gauge or metric versions. The low-connected aluminum back-flanged case can be easily liquid filled in the field using the appropriate conversion kit.
Gauge size: 4 ½” and 6.

    • Liquid Filling
      • Order Code: LG, LS, or LM - Extend the life of your pressure gauges. Liquid filled pressure gauges are generally recommended over dry gauges due to performance and durability. When USG’s liquid filled gauges are filled with Glycerin (LG), Silicone (LS), or Mineral Oil (LM) you’re helping to prevent gauge failure commonly caused by excessive vibration or pulsation. Glycerin is the most common fill fluid and is typically used for room-temperature applications. Silicone is used for more extreme temperature applications. Mineral Oil can also be used for higher temperature ranges.
    • NIST Calibration Certificate
      • Order Code: /C - NIST (National Institute of Standards and Technology) Certification of Calibration states that the pressure gauge was tested at multiple test points and is within its stated tolerance of accuracy. Gauge is shipped with a sticker on the side of the gauge noting the certification number and date, and NIST certificate.
    • Dual Scale Dials
      • US Gauge offers most pressure ranges in dual scale, such as psi & kPa, psi & BAR, psi & kg/cm2, or single scale metric such as kPa, kg/cm2, or BAR. Dual scale dials are available at no extra charge. Please reference our data sheet or email customer service at with any questions.
