SOLFRUNT 1980 Brass/Phosphor Bronze Pressure Gauge

Accuracy: ± (0.5 % FS)
Size: 4½” (114mm)
Wetted Parts: Phosphor Bronze and Brass
Ranges: Vacuum – 30 to 0 “Hg VAC (counterclockwise rotation)
Compound – 30″Hg VAC to 150 psi
Pressure – 0 to 1000 psi

The SOLFRUNT 1980 process gauge is available with brass/phosphor bronze wetted surfaces and a solid front PET case. Brass/phosphor bronze is a lower cost option in pressure gauge applications that do not need 316 SST or Monel.

The 1980 process gauges have a solid front PET turret style case for chemical and petrochemical processing applications. The PET material gives this case superior impact strength and a broad spectrum of chemical resistance. They are available dry or as liquid filled gauges with an EZ Fill case. The EZ Fill case is designed to facilitate filling in the field without special tools.

The 1980 process gauges are supplied in 19 vacuum, compound, and pressure ranges from 30" Hg vacuum through 1000 psi gauge pressure. Dual scale dials are available for every range.
Gauge Size: 4-1/2"


    • 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.
    • High Visibility Yellow Dial and Red Pointer
      • Order Code: /YB for dial & /RP for pointer – High visibility bright yellow dial and red pointer make your pressure gauge easier to read in any lighting, during the day or at night with a flash light.
    • Glow-in-the-Dark Dial
      • Order Code: /LUM – The dial is wrapped in a rechargeable, durable, “glow-in-the-dark” vinyl formulated by 3MTM. This film recharges with as little as three minutes of exposure to sunlight, fluorescent, or incandescent light, but longer exposure will improve performance. Glow-in-the-Dark dials provide users with improved visibility for gauges that need to be checked at night, or in low light situations.
    • 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.
