What it is

The Regin J Gauge Fluid S.G.1.99 is a manometer fluid supplied by Regin for use in the REG U30 J-gauge. It forms the liquid column that indicates pressure on the gauge scale. The fluid has a specific gravity of 1.99 and is specified for the REG U30 only.

Signs this part needs replacing

  • The fluid in the gauge is discoloured, cloudy or visibly contaminated
  • The fluid level has dropped below the zero mark on the scale
  • Readings are erratic, jumpy or inconsistent between tests
  • Fluid has been lost through spillage, leakage or a damaged gauge
  • The gauge has been left open and the fluid has absorbed moisture or separated

Before you order

  • Confirm the gauge is a Regin REG U30 — this fluid is specified for that model only
  • Check the specific gravity your gauge requires; this fluid is S.G. 1.99
  • Inspect the fluid currently in the gauge for contamination before topping up or refilling
  • Check the gauge body and tubing for leaks or damage that would cause further fluid loss
